Bug new and old interface

Also, the new part of the panels works differently, it does not load when changing the class, but switches immediately. If such a system is better, then it is advisable to assign it to the old part of the panel(which is being updated) so that it works stably. In the screenshot, I tried to capture the update of the old part (the darkened part), and the instant change (the light part)

Yes, this is a problem related to this addon.
