No. I use this all the time and don't have issues turning it off. When are you turning it off? After the remote start, but before or after pressing the start button to turn everything on?
I could see that being an issue. It might turn it on with the remote start, then turn it back on when turning the Jeep "on".
There is also a lot going on during startup and power on from a CANbus perspective. It's possible the CANbus signals the seat to power on (IF that's even on the bus), then cycles back around to make sure it did, and if you've turned it off, it might issue the on command again...... maybe, ... sort of..... kinda. Logging the CANbus messages might reveal what is going on there.
