Strange doorbell operation

Hello,We have a Ring Video Doorbell connected to a Westminster chime. Things work fine, however, twice since it was installed, the doorbell starts ringing and continues until the doorbell button is pushed. When pushed, the blue and white lights chase themselves around the ring and then the doorbell stops ringing. We get no message on the phone or on the Alexa. There is no evidence of power interruption or anyone at the door. The first time this happened it was during the day and last night it was at 3 am.Anyone else experiencing this and is there something to do to eliminate this false door button push response?
