Overspeed issues at 320kts

I am flew actually with the Airbus 319 and get the Overspeed warning. Thats no problem to me but now i am back from Grade 3 to Grade 1 with 6 violarions for no reason.Normaly i am Grade 5. I am really angry right now. I have a Video from the issue

How high were you?

Flying past the red tape for I think 20 seconds gives you a violation.

Could you please provide us the video?

Cant upload MP4 Video pffff

No problem! Did you got the Violotations below 10000ft?

Don’t need to upload the video. Just need to know your altitude.
