That is too warm for your snake!
The hot side belly temp should be around 90F!! Ambient/cool side should be around 80F!
With a tank of that size you definitely do not need 2 UTH! You want to provide a heat gradient with one end wamr (90F) and one end cool (80F)! Remove one UTH for sure.
The thermometer probe should be attached to the inside of the bottom of the glass, atop the middle of the UTH. The UTH probe should be on the outside between the glass and the UTH stick side - although some people put it beside the thermometer probe inside the tank. Both can work fine.
You should be measuring and adjusted the heat for the hottest part that the snake can reach - which the the bottom of the glass. This is not just for ball pythons who enjoy burrowing.
Thank you for providing all of that information though. I personally appreciate it, as it makes answering your questions much easier. I wish everyone did that
