Ruleset doesn't recognize modules

[blackturtle71]

Hi, I downloaded latest beta (0.6.3), first of all ruleset isn't compressed into .pak, but I did it manually (just zipped and renamed extension from .zip to .pak). After I did that Fantasy Grounds recognized the ruleset, but it doesn't see any attached modules (like bestiary) except for the Calendar module. I also tried loading 0.6.2 ruleset which actually recognized all the modules, although ruleset itself has dice rolling errors.
So, any idea how I can make 0.6.3 ruleset activate witcher modules?
