MS-OPS2 controls other switces

Hi, I recently connected my MS-OPS2 sensor. I only had black wires and no ground inside the switch box. I connected one black wire to the black wire on MS-OPS2 and there were two other black wires (one pushed in and one screwed to the side of the old switch) which I connected and pig-tailed with the other black wire in the MS-OPS2. For the ground, I connected the bare wire and the green wire to the ground within the box. Now my sensor worked great but it ended up controlling four other switches in my bedroom and bathroom. I know that the issue is with the hot wire not passing through to the rest of the circuit but I have no clue how to fix it. I tried all permutations - either the sensor doesnt work or it controls all the switches. Your advice is much appreciated.
