Would there be any odd reasion why my 3 month old BP would be wanting to sleep on the old glued on temp dial on the side of the tank?

I checked the UTH temp and everything is normal, humidity normal, eating normal, she seems normal untill she goes to sleep. she refuses to use her hides and feels more inclined to sleep off the ground and as high up as she can get. I placed some balled up toilet paper under the dial because she will fall off after a while.

I cant take the dial off due to it being glued and she is not yet ready to go into the rack.

Should I take her to the vet? or is this something that some times happens?

could use any tips, tricks, or advice you might have.
thanks every one.
