[Closed] issues with translations of categories

Hi. We face some issues with translations of categories with WPML plugin on our website: hidden link

For example:
This is the link of thе bulgarian category:
hidden link
(Bulgarian is main language of our website)

This is the link to english version of that category:
hidden link
It appear as missing page with error 404

When i go to Settings > Peermalinks and refresh them, when I am in english version of the administtration, the english links start working fine, but the bulgarian links break and show error 404.
When i switch the admin to bulgarian and refresh the links again, the bulgarian links work fine, but the english links break again.

Can you assist us to find solution for this case.
