Build items not unlocking

I have downloaded the Discover University pack. However, the items are not unlocking even after I meet the criteria for it. I removed the mods I have to see if that was causing it, however it was not.

I have the cat & dog pack as well but haven't had any issues with that one. I haven't had any other issues with the game except for this pack not unlocking my items when I've met the criteria to unlock them.
