Happened to me too in EFHK. This is P3D v4.4, and I'd done a complete GSX deinstall/reinstall after upgrading to 4.4 since I'd updated the Client, Content, and Scenery.
Certainly looks like some issue with SODE, where the bottom of the model moved but the top part didn't.
But what's weird is... I saved the scenario, and when I came back to it after restarting, the same jetway had a different livery, and worked normally.
