Constant Recent Alarm Message

I’ve had my Simplisafe system since 2019 and never had an issue with it. Recently, however, every time I turn the alarm on “away” mode, it tells me there’s been a recent alarm trigged by a motion sensor when I return.

Ive tried un-adding and re-adding my motion sensors, but that didn’t fix it. Any ideas on how I can fix this issue? I checked with my neighbors and confirmed my alarm isn’t going off every time I leave the house, so it seems like there’s some sort of glitch in my system.
