I think I see what your problem is....
You misunderstood SPDIF and ADAT...

ADAT = 8 digital channels 4 left and 4 right.
SPDIF = is ONLY 2 channels just like your main out L+R.

Some interfaces if there is an adat then ONLY 1/2 can be used as spdif.
But if you configure for adat then all 8 will be adat, same connector maybe but different config.

So if you are on spdif then you ONLY get 1+2 clear and good. All the others will not be used with spdif. This is what I've witnessed on many interfaces.

again....

Adat = 8ch digital, all 8 used.
Spdif = 2ch digital, 3-8 not used.
