1. If the snake is going into shed that might be a reason, check for pink belly and eyes turning blue.
I dont think she's in shed.
2. Check for mites by looking into the bowl with a flashlight and if the snake has mites you'll see black specks in the bottom.
She had mites about a month and a half ago, but all are gone now. Thank god!
3. Over-heated snakes will soak to hide from the heat, check ambient temps and hot spots.
All temps are good right now.
4. Short of those reasons some snakes just enjoy soaking but I always go through the checklist if I see a snake soak
