I am trying to use a Max() combinator to filter multiple input signals so I can turn on and off output pickups in my factory so only the highest of them will be turned on. I also want to leave a little bit in them so I was subtracting a value from each input and using a decider combinator to filter any negative numbers (i.e. below the hold threshold) before I put them into the max.

This is where things get weird. It seems that the filter is being ignored and the max is being output even when all of the sampled inputs are being filtered by the decider combinator. So all inputs to the decider are negative, there is nothing listed on the decider as an output, but the Max() combinator is still functioning as though the Decider wasn't there.
