    Well if that indeed is your top level schematic, you have wired channels A...H and the trigger all to the same 16b bus.

    So it is not surprising at all that logic is eliminated.

Well, it did, but the issue my colleague acknowledged above wasn't the root problem.

I was using a problematic parameter register, which had been truncated for some reason, and thus some inputs, in this case CHANNEL_A_mon_i and CHANNEL_B_mon_i, were not properly connected, leaving some unused logic paths as mentioned before.

Also, @_AK6DN_ said that connecting several paths to the same buffer would create redundant logic that would later be eliminated by the compiler. But now seeing the problem I disagree with that statement.
