Obviously the gate connection of your module to the bus is made already with a 220 Ohm resistor. So it's one of the newer modules.

If you want to combine gate or trigger signals the A-186-1 Gate/Trigger Combiner should be used. As a rule outputs should not be
connected because it's generally not a good idea to short outputs. In most cases nothing can be damaged within the A-100 but the
results are unpredictable. For the combination of audio or CV signals mixers (A-138) should be used, for Gate/Trigger the above
mentioned A-186-1 (or also mixers).
