False Alarm at 1:42 in the morning...

I've had my ring security system for about 2 weeks.  I have a bunch of ring open/close sensors and one motion sensor.  I also have a ring doorbell and 4 ring cameras.  I had the system armed/home while we slept and was awoken to an alarm at 1:42AM.  I got my gun, turned off the alarm and checked the house.  Nothing.  I checked the app and it said my patio sliding door sensor was tampered.  Its 8' high on the top of the door.  It seemed fine.  Am I going to be able to trust this system??  Why would this have happened??  Can I disable a tamper from setting off the alarm?
