PortraitPro Studio Plugin disappeared from the filter menu Elements 21 (iMac Catalina)

I have purchased the latest version (21) of PortraitPro Studio. Installation was easy. When opening Photoshop Element I got the message to give permission for the plugin to be installed in Photoshop. No problem at all, that also went well. PortraitPro was in the filter folder under the name Anthropics.
When I wanted to use it in Photshop it was still gray. Somehow it hadn't gone well with the activation of
and I still had to activate that in PortraitPro's stand alone program, which also went well. I also had to do the same with the program Smart Photoshop editor, also a program from the makers of Portrait Pro. Only when opening Photshop Element, PortraitPro studio was no longer in the Anthropics folder. The other program is still there. The strange thing is that the plugin is in the application folder plugin of Photoshop Elements.

I've made many tries, removed and reinstalled PortraitPro. But I can't get it back in the Anthropics folder in Photshop Elements. Is anyone familiar with this problem or does anyone know how to help. The PortraitPro helpdesk has not been able to help me so far.
