How are you measuring the temps and humidity? If it's from those two dials stuck on the girls' tank, then the numbers are not only wrong, they are not from either end of the tank.
#1 problem I see. The two girls are in one tank. Two snakes in one tank will constantly stress over the best place in the tank, and struggle for superiority over each other. You should seperate them. Note, they are the ones acting odd too?
#2 problem. I don't see any way to hold in humidity. The screen lids are notorious at letting out any humidity, so that it will be too dry.
#3 problem. The girl tank, you might want to move the hides, so that they are on each end of the tank.. instead of one in the middle, and one on the end.
#4 problem. THe pinstripe hide that is a half log, many snakes don't feel secure it those.
Please post what you're using to measure the temps and humidity, but I think one of the main issues will be that you have two snakes in that one cage, which means they will not be comfortable at all, since they spend all their time fussing over which snake is dominant.
