I had this same problem. As the AS v1.0.6 installs in Community folder, I had to delete the Marketplace v1.0.5 (via Content Manager) from the Official folder. So delete the original one that says 'up to date'. Easy to do and all works fine.
I have just uploaded Paderborn v1.0.6 via the AS site. When installed the file is located in Community Folder, but the previous file (July 2021) is still located in the Official Folder. Should I delete the 'official' file or doesn't it matter?
