Menu bug when store change url from .de to .de/fr

[david-kaplan]

Hi fellow developers, thank you for your help. 
1. I published French language. Get automatic URL rukatech.de/fr 

2. When I am on the .de version everything works fine. On .de/fr the main menu doesn't work. It works on mobile but not on desktop. How it "works" is in the video.  
Online store is here. https://rukatech-filter.de/

One think I noticed on .de version. Notice the <a href="#">

On de/fr version. notice the <a href="/fr#". 

That is probably at least a part of the problem. 
In Shopify Navigation is the top link "Fabricant" set to # so I can use it only to open up the rest of the navigation. 
This is a code for the theme. header. This is for the whole picture. Below the snippet there is a part I suspect is the problematic one. 

        theme.headerNav = function() {
            var e, t, i, n, o = "#HeaderWrapper",
                s = "#SiteHeader",
                a = "#LogoContainer img",
                r = ".megamenu",
                c = ".site-navigation",
                l = ".site-nav__item",
                d = ".site-nav__link--has-dropdown",
                h = ".site-nav__dropdown-link--second-level",
                u = ".site-nav__compress-menu",
                p = '[data-type="nav"]',
                m = '[data-type="search"]',
                f = {
                    hasDropdownClass: "site-nav--has-dropdown",
                    hasSubDropdownClass: "site-nav__deep-dropdown-trigger",
                    dropdownActive: "is-focused",
                    headerCompressed: "header-wrapper--compressed",
                    overlay: "header-wrapper--overlay",
                    overlayStyle: "is-light"
                },
                v = {
                    namespace: ".siteNav",

                if (t) {
                    var i = t.offsetHeight;
                    0 !== i && document.documentElement.style.setProperty("--header-padding-bottom", i + "px"), v.subarPositionInit || (e.classList.add("header-wrapper--init"), v.subarPositionInit = !0)
                }

This is what I suspect is problematic. 

                            theme.config.isTouch && document.querySelectorAll(d).forEach((e => {
                                e.on("touchend" + v.namespace, (function(e) {
                                    e.currentTarget.parentNode.classList.contains(f.dropdownActive) ? window.location.replace(e.currentTarget.getAttribute("href")) : (e.preventDefault(), o(), i(e.currentTarget))
                                }))
                            })), document.querySelectorAll(h).forEach((e => {
                                theme.config.isTouch && e.on("touchend" + v.namespace, (function(e) {
                                    var t = e.currentTarget.parentNode;
                                    t.classList.contains(f.hasSubDropdownClass) ? t.classList.contains(f.dropdownActive) ? window.location.replace(e.currentTarget.getAttribute("href")) : (e.preventDefault(), a(), n(e.currentTarget)) : window.location.replace(e.currentTarget.getAttribute("href"))
                                })), e.on("focusin" + v.namespace, (function(e) {
                                    a(), n(e.currentTarget, !0)
                                }))
                            })), theme.config.isTouch && (document.body.on("touchend" + v.namespace, (function() {
                                o()
                            })), t.querySelectorAll(r).forEach((e => {
                                e.on("touchend" + v.namespace, (function(e) {
                                    e.stopImmediatePropagation()
                                }))
                            })))
