I can't view installed actions

I installed previously purchased actions into the Photo Effects folder and they are not showing up in the thumbnails under effects. I can see the purchased effects listed in the Photo Effects folder along with the PSE 16 ones, but they don't show up when "show all" is indicated. I followed all of the steps I previously used to install/ use purchased actions. I did rename the mediadatabase file so that it would reload upon opening PSE 16. Suggestions?
