Yes, Bogertrophis is absolutely right and gave me the same advice a week ago, and it worked! As soon as I stuffed some crumbled paper towels into the hides, my snake started using them. By the way, here is my little girl doing the same thing as your snake. I ended up removing the styrofoam decorative background and it looks better without it. And, the background makes a perfectly fitted cover for the top of the enclosure to allow for some airflow while blocking drafts and keeping in some humidity.
And this is her tail sticking out of her hide after I put some paper towels in there to lower the ceiling and make the doorway smaller
