I can't remove dashboards

The problem that arose is the following:
I tried adding a new panel to my desktop and a recycle bin widget however, I didn’t like the way it looked so I decided to delete them. The problem is that once I restart my pc or turn it on again, they reappear even if I have deleted them

Hello and Welcome on the forum.

I see before this same problem before and I have reinstall the system again for.

:+1: Welcome to Manjaro! :+1:

Does this also happen when you create a new user and log in there???
