Downloading packs

I recently purchased my first subscription based CD 2024. Upgraded from a bought CD of X8.
I downloaded 3 free packs to add to the collection but only one actually worked the way it is suppose to. Two of them I downloaded, installed and then I couldn't find them. They have been removed from the list of packs to download but I can't find them anywhere on my system (Windows 11).

Has anyone else had this happen or any suggestions as to what I need to do.

Thanks in advance.
