ATEM Television Studio HD - mix minus not working

Hi,
I have a problem on my ATEM Television Studio HD. The mixer has the option for mix-minus on the 4 sdi channels, but does not do a mix-minus on that 4 channels...

It makes no difference on the oputputted sound on out 5 if i check the option for mix-minus or not - the sound of sdi IN 5 will pass the mixer an goes out on the same output (SDI OUT 5).

Also tried all other channels (6 to 8) - none of the channels are doing mix-minus!

SW Version is 8.1.1 - my ATEM Software on my Notebook is 9.3.3, but I don't get the option to update the mixer...

Any idea?

Thanks
Tom
