This happens if I return 2 stereo bus. But works correctly with a returned 4 channel bus.

Could this be caused by the VBAP panner? Does bypassing the panner help?

Actually bypassing the VBAP panner "causes" this problem.

This is how the situation looks:

If the VBAP panner enabled on Stereo Bus 1 and 2 then:
- Bus 1 is not returned, there is no sound on 1-2.
- Bus 2 is returned correctly to 3-4.

If the VBAP panner bypassed on Stereo Bus 1 and 2 then:
- Bus 1 is returned correctly to 1-2.
- Bus 2 is returned with the described mono sound to 3-4.
