Free DLCs not available if game is family-shared on Steam!?

Hi deck13, can you please fix this?
My friend has the surge complete edition in his library and we have family sharing. I don't know why but only the purchased dlcs like creo world and employee kit are available when playin the game as shared in library, while the free ones are not available
Can you contact steam and fix this? I head something similare already happened in the past and it was fixed by the devs contacting steam

Hello, is he able to add the free DLC manually on his side?
