Can't add apps to panel

New install (v.21) and it’s different from last time (v.20.1).
Now, when I right-click on a menu item “Add to panel” it instead adds a full Panel launcher.
It used to just add the app’s icon.
Does anybody know why or how to fix this?

Hello @doodah! Now you said that if you click “Add to panel”, it adds a full panel launcher, right? That may be because you’re current panel isn’t compatible with widgets. Either way, choose “Pin to task manager” instead of “Add to panel”.
