Maybe you need to select the Save and Exit option when you want to leave in the middle of an active patrol. If you merely exit you lose the patrol and start over in the next one.
I had the same problem. With save and exit give the exited patrol some identifying label - like "Miss1 A" meaning first patrol, first exit. Then it will load the next time you start the game.
I think I'm right here.
