Here is short update: after re-doing segment driving part, it turned out yet another failure, very similar in behaviour with the mode of the first, 8-digit attempt, all digits lit all their segments no matter what input.

I thought that I had one extra invertor in my circuits, but now it seems to me that probably I should have added yet another one to each segment driver instead of getting rid of it.
