The tempo automaticly from 120bbm to 63?

I was playing on the electric guitar KONTAKT from Native instrument
During the recording, I was surprised that the time changes from slow to fast and from fast to slower. Is there anything wrong that I do? i tried also with scaler the same problem

It sounds like you may have accidentally done a tempo change. Have you added a tempo track to your project? If so, open it and see if you have tempo changes recorded, and if so, delete the unwanted changes.
