DLC for a game on mac not showing up after I bought it

[Mrscarybananaman]

When I bought the bundle for all the dlcs(for a game called The Binding of Isaac Rebirth) I downloaded it on my pc first(and it worked fine). Still, when I went to download it on my Mac it showed that I could only download the other dlcs that I bought with it and when I tried downloading the dlc from the store it just launched the game. And when I try to see the dlcs for the game it only showed rebirth and rebirth+ dlcs. Also when I tried to launch the game it showed an error and didn't launch. I've tried resetting my cache and redownloading the game, and none of those worked. pls help, I beg of yall.
