PX4 v1.14 Flying Wing: Massive roll/pitch setpoint switching from Manual to Autonomous mode; caused crash

First time posting here, so forgive me if I leave out some crucial information.

The issue I’m having is that when switching from a manual mode to an autonomous mode the pitch and roll setpoints have a step change to very large values. I have experienced this on two flying wings (1 home built, 1 E-flight Opterra). The first incident led to a crash. The second time I made sure I had sufficient altitude before testing. Below are the details and flight logs.

Any help is appreciated. I don’t know if this is a potential issue with the hardware, the PX4 v1.14 firmware, or if it is specific to the flying wing airframe selection. Both aircraft flew fine in manual modes (manual and stabilized) before the incidents.
