halo Mcc I need help

When I go to play campaign on all the halos it tells me that Missing content you need to have halo ce campaign installed. Would you like to to customize your installation now then it brings me to a screen where it shows me that I have all of them installed. I tried uninstalling that did not work (it doesn’t work with multiplayer and all the halo games)

Which store did you use to purchase and install Halo MCC? Steam or MC Store/XGP?
