I have all of the effects packs and now they are not showing up in the application. I disabled them and restarted Squash, then re-enabled them. I only get the icon for the App and Get More. The app is up to date Version 3.0 (812) and I am on MacOS Big Sur 11.5.1
Solved. I trashed the app completely from the Mac, re-intalled it. I had filed away the two filter packs and was able to install them. All is well.
