Link-Confusion with language plugin

Hi and thank you for the support-work.

My problem is that I´m trying to set up projects, employees, posts, etc and use the PolyLang Plugin to structure them into different languages. But as soon as they are changed with PolyLang, I cannot call up the post itself anymore, while it is still displayed when searching for its category.

I hope you understand my problem, I cannot give a link as the server has restricted access.

Thank you for your help

solved by setting permalink > default.
