Hello,
We do have a way to clear out the apps created by Patch My PC, it is definitely easier to start fresh sometimes!
If you open the Patch My PC Publisher, Navigate to the "ConfigMgr Apps" tab, hit "Options", you'll see a button for "Run ConfigMgr Application Manager", in that tool you can mass delete deployments as well as the apps themselves. If you do have deployments on the apps, I do recommend deleting the assignments first, then deleting the apps (sometimes software center gets confused when the app is deleted and the deployment isn't deleted first).
