Random rings from mechanical doorbell

Recently, I've been getting "phantom/random" rings from my manual doorbell , when no one has pushed the button on my Ring Door Bell Pro. These "rings" do not show up as events on my Pro doorbell and they seem to happen at random. Anyone else experience these issues? Again , my old hardwired doorbell goes off randomly ( no button push ) . No video , or alert . I also have a chime it does not ring unless the button is pushed
