Crow Banker and Merchant Placement Issue

Wildberryjack

If you access them from the rear they permanently turn 90 degrees to their left. I end up having to reposition them every time. For reference, I have them on the banister in one house so they can be accessed from the front or rear. Yes I can move them or make sure to access from the front only, but it seems though that they should not reposition after access from any direction but they do.
