Hello. I have 3problems:

  1. In the source code view-source:https://merch-ua.com/ I have a block for specifying alternative language versions, and it looks like this:

I need to change it to a new one, where can I do it?
  1. When creating new language versions, I created two pages related to the same language:

I need to remove /en-ua/ to leave only /uk. How do I do that?

  1. Where can I change the sitemap.xml file? Because the this file contains pages /en-ua/ that I want to delete.

Thanks!
