Multiple Shift selection ascending to incorrect selection.

Hiya, a new bug I’m afraid.

Normally in Cubase when I select multiple tracks in the mixer I can then hold shift and select an output and all tracks selected will change to that output, or input or whatever I’m changing, bit like qlink does.

Problem is when selecting and holding shift whilst selecting output, 1 or 2 will change to selection but others ascend.
So if I have:

Stereo out 1
Stereo out 2
Grp 1
Grp 2
Grp 3

What will happen is a few will be Stereo out 1, but other ascend and become stereo out 2, then grp 1, grp 2 etc, then I’m having to rechange manually the tracks which changed to the wrong outputs.
