Retrofit alarm kit showing tampered

Good morning, I recently installed my Retrofit Alarm kit. I tested each sensor, and they all work. The base station chirps when I open any of them. My app keeps showing an error for all of them saying they have been tampered with. I have replaced the cover on the retrofit kit, I have tried to open and close the error in the app, but nothing has cleared it. How do I get rid of this error message? Thanks!
