Unable to change language and connect

https://ibb.co/GvCk7f9 Please check this image … Why I am unable to change language or connect the category to another category?

It is somehow connected to another issue where one category/product is connected with 4/4 languages but one language of it is connected only to 2/4 or 3/4 languages like here – https://ibb.co/tK98F5g

And this all is maybe somehow connected to another issue – when category slug in language 1 is same as category slug in 2nd language – for example:

slovak language is my default, english is translated example.com/sport and example.com/en/sport …. then when I am on slovak version and click in menu on Sport category, I will/can get redirected to the english translation … its very bad functioning

Please answer me asap with the solution to this, thank you

Also another problem how it happened is that when I was bulk translating(duplicating to other language) the posts, somehow few products or categories got greated 2x … and some of those categories/products are “healthy” so they dont have such problems as this … and some are faulty … this is really bad experience
