Background & Board Theme change when I Sign Out

Background & Board-Theme always change whenever I Sign Out. They change into default (White Background and Brown Board-Theme).
This was not the case before but it started happening recently and it's not fixed yet...

So whenever I Sign Out, I always have to change my Background to "Dark" and my Board Theme to my desired one... it's very annoying... can you please fix it?

I don't have this particular problem, but every time I sign out it resets the board geometry to the very beginning of the slider, making the board super small.
