Same module working/not working on different pages - by: Ludomir

Hello and thanks for sharing such a useful tool.
However I have a problem with rendering of the same module on different pages.

I managed to translate K2 items without any problems, but on their pages, the easy language is not working.

example 01 - WORKING (Module > Case Studies)
LINK: logomir.biz/dzumla/index.php/en/about


example 02 - NOT WORKING (same module > displaying {LANG EN}CASE STUDIES{/LANG} {LANG SR}PREDSTAVLJAMO{/LANG})
LINK: logomir.biz/dzumla/index.php/en/b2mv

I didn't find similar problem anywhere on the net, could you please help me out because my site is nearly finished, but i still have problems with multilingual content.
Hope my explanation was understandable. Thanks a lot in advance and have a nice day,
Ludomir
