Warning: Unknown flight Mode "Return" (default:unknown:0)

Hi everyone. I am currently working on PX4 Offboard Navigation with Python and ROS2, using Ubuntu 22.04 and QGround Control. On my first simulation when I try to return to Launch point I get the following error:

Warning: Unknown flight Mode “Return” (default:unknown:0)

It’s seems like a QGC error because there are no log on this error in px4 terminal, only on QGC terminal.

So if anyone knows how to solve it, please let me know.

Note:I have tried different version of QGC, with same result.

I have solved it. There is a bug in the current version of QGroundControl V5.0 - Stable (Latest). It has been solved by installing the QGroundControl v5.0 - Release Candidate 1 (Pre-release).
