V1.12 with CUAV X7 Problem

Dear Dev Team,
I just uploaded my CUAV X7 controller with the 1.12.0 stable version, but got some problems in the test flight.

Firstly, when I fly the quadcopter at the position mode, it sometimes shows the below warning on QGC.
Then I use the mission mode, and when the drone comes back to the land point, the drone suddenly rolls at a very big angle to the left side, please check the log below.

When I use the 1.11.3 version, it’s without any warning and working well.


Thanks a lot!
