Upgraded Theme - Lost Predictive Search Results Sizing

I was using Refresh Theme version 13.0.1, and there is a new version of 15.0.0; I’ve been worried about my PageSpeed and several other factors, so I thought upgrading the version might help. My first major goal is to get approval on Google Merchant Center, and I thought maybe upgrading the theme would help.

Since I upgraded the theme it made me lose quite a bit of my custom coding, but I can’t figure out why I can’t get the predictive search results on my search bar (desktop view) to appear the same length as the search bar - it isn’t really showing at all, just a narrow line. I added an Ezfy-search snippet for the search bar for this, if you need to code please ask, or if you can inspect it. Note: The predictive search works fine for mobile view!

Here is my website with the new Refresh version: https://mankave.store/?_ab=0

Here is an image of the element I’m having issue with:

Can someone please guide me on how to fix this "predictive-search’ element to show as it should?

If you have insights about upgrading theme, or Google Merchant Center please advice as well.

Regarding Google Merchant Center, while I do specialize in Google Shopping, changing theme will generally not be the solution to get approved. There are lots of areas that you need to look at.

I recommend comparing your website and business against these policies:

I’ve had Simprosys look at it and give it the all clear, then I hired a guy on Fiverr to evaluate it after I was still denied. He pointed out some good advice, such as improving PageSpeed Insights score, Siteliner.com showed I had a broken link for my ‘User-Accounts’ icon, and some other issues. I’ve been working on this for months, so I’ve read all those suggested pages 100x.

I hired another guy on Fiverr to get it approved, but I’m not sure how that’s going to work out because I haven’t noticed him do anything as of yet (4 days later). I do believe I am getting close though… I’ve also seen a lot of your videos.
