two identical cave-like (meaning one opening) hides are the most suitable and most used hides for beeps since they offer more security than the hides you currently have. the RBI hides linked my MissterDog offer this for your snake.
if we look at your hides (im recalling from memory): they are not identical, one has two openings, and the other has one large opening.
clutter is a definite must. along with proper hides, clutter will help the snake feel less exposed and less stressed.
if i recall, your temps were good could you give us a temp rundown again?
