Light fixture wonít turn off. Single pole with 3 sets of wires

Let me begin by saying that I know nothing about home electrical systems. I take that back. As a child, I learned that Getting zapped sucks. Hereís the run down: I wanted to change my light switch in my garage to one with a motion sensor. I pull the old switch and notice there are 3 sets of wires. All the white wires bundled together as are the 3 grounds( bare copper). The one black wire is attached to one screw and the two other bblack wires are twisted together with an extra piece. Iím assuming for easy connection purpose. I had a little bit of trouble but eventually Iím successful at upgrading my switch. Thatís when I learn that thereís a difference between a vacancy switch and an occupancy switch. Obviously I installed the one I didnít want. I buy an occupancy switch and wire it exactly as I had the vacancy. To my surprise , itís working. Almost. The light is on. LED is on. But thereís no change when I push the on/off button. I can here it clicking but the fixture remains lit. I try switching up the black wire combos. Flip flop the line and hot wires. LED is now off but the fixture is still on. The switch isnít clicking anymore either. To add to it the light and vent in they laundry isnít working either. That switch is located on the other side of the wall Iím working on. Bonus! Some of my other lights arenít working as well. Porch light and aquarium light which is plugged into a socket. Any help would be greatly appreciated.

Welcome to the forums.

All the whites stay tied together.
The single black wire is the load/light.
The two black wires that were tied together with a tail connected are hot and must remain connected together.
