Can't Activate DLCs On GFN

[kinginthehome]

Hi guys, I just bought the game on Epic Store and with all DLCs. Also i want to play the game on Geforce Now(GFN). BUT problem is when i enter the game and check if DLCs are installed there is no "filled" icons left bottom section where DLCs icons stands. Also I can not find DLCs on Mod menu too. Why this is happenning and how i can fix it? or should i refund the game and buy from Steam (cuz Steam version have autoactivation). Second option is not i want to go with cuz i took a good discount on Epic Store. Please help quiick!

Regards,
