Multilanguage support

After 8 month, this issue is still relevant:

I have multilangual page via Polylang. How can one use different page per language? Whem I try to do compare on EN page, I am redirected to CS version (/cs/porovnani/?compare=37234,37236). Yes, in my plugin settings is CS page. But this one is translated via Polylang.

Main problem is that, if I do compare on EN page, products are in czech. When I replace URL for EN one (/en/compare/?compare=37234,37236), it works well.

The page I need help with: [log in to see the link]
