Ride Rite problems with relay?

Had a random problem just wondering if anyone else experienced the same.
I have the Ride Rites (F3wireless) wired to my Switch Pro. The Switch Pro is activated by an ignition fuse. Switch pros not set to delay when shutoff. System has been good for the last year.
I noticed a few days ago my compressor was running, after shutting the engine down and exiting the truck.
It stopped after leveling to preset psi, but I unplugged the compressor at the motor anyway so I wouldn’t wake up to a dead battery. I hooked it back up this evening and noticed compressor passed by the 20 psi preset level and would not release air to level back out. I’m think this might be the relay on the Ride Rites. I guess it could be the ECU seeing hot it didn’t stop at preset psi ....
Anyone experience this? I left it disconnected for now.
