Polylang issues

Hi, I am using Polylang for translations in Catch responsive free version: http://solveprague.cz however I have 2 problems: 1) the featured slider is not changing when switching languages. 2) featured images remain the same for EN and CZ pages. If this could be solved easily by purchasing pro version I am fine with bying it, but I need to be 100% sure this will work in pro version. thanks a lot, Petr
