Hi! I'm sorry the last update has caused some trouble, I have put a small explanation in the add-on description.

The right-click functionality has been improved again in version 5.2.4.

If you have an export of your list from the old version, you can import that file in version 5.2.4. If not, you can downgrade to version 2.0.1. to make an export first (your channels should still be there).
