I can imagine it’s there but I have no access to the “remove panel” button. The top of the options panel is hidden by the panel which has been set on top of the screen.
The best thing to do here would be to select a different "Global” theme (select “Use desktop layout from theme”). This will set desktop items to that theme default and remove those panels and then you can start fresh from there.
Actually, one need to enter the edit mode and then alternate right clicks and left clicks on each of the created panels. The option “remove” is offered there and must be confirmed with a second click. At least 4 or 5 clicks to get rid of the thing!
