I had it happen on ALL my sights as well - and I don't have a lot of sights with SnapAV stuff left. It was one of many reasons I dropped SnapAV last year.
Ovrc is just BS when it comes to actually knowing what is going on. It never tracks right and doesn't always log everything it is suppose to. Pretty useless even for free.
Those who 'think' it is working perfect for them... I would challenge you and say, you don't realize what it is not doing that it is suppose to.
