Hi Support team!
I have found a bug with translating Portfolio Meta Fields, so portfolio meta names(Skills, Project url, etc.) are not updated to the current language. It only happens with AJAX portfolio mode, in usual portfolio item page all portfolio meta names are taken as they should with corresponding language.
To see the problem, you have to enable two languages with wpml and write different portfolio meta names in each language. Depending from which ADMIN language you will save, portfolio meta names will be the same on both languages in the frontend, and second language will be ignored.
For example: I have translated different portfolio meta names (Skills, Project url, etc.) for each language, but if my admin panel is english and I save some changes, both languages will show english portfolio meta names(Skills, Project url, etc.). Same thing happens if my admin panel is russian and I save some changes, both languages will show russian portfolio meta names.
I think this problem lays not in the WPML plugin functionality(as I said in the usual portfolio item page it is ok), just AJAX should be updated somehow.
