Different Layout for Desktop Error

Hey guys, after i moved my second monitor didn’t save my configuration where which widgets where placed, and so on. So i rebuilt it. Now every boot the old configuration or the new configuration appears on my second monitor, i can’t seem to control which one is chosen.

e.g.: old configuration has taskbar on the bottom with Sticky notes containing stuff, new configuration has taskbar on the top without sticky bar but CPU Temperature Widget.

I suppose, there is a location for the config somewhere, and the best idea would be to delete one of both, so only one layout can be chosen.

Thanks for any help, happy to provide more information!
