I merged two identical threads into this, the other already contained a confirmation we are aware of it, which I'll repeat here:
I think it always happened before though, you just happened to noticed it now, since we never had any code that would disable automatic door opening for the rear door if the rear stairs has been disabled, since the automatic door handler is part of the airplane database, while the rear staircase disabling is part of the airport profile, so they don't usually share data with each other.
