Its an accepted part of driveline operation.
Second one,.....You should be taking your flex assy apart after every run. Then clean and regrease. Not on the second or third. Its part of a maintenance plan you should adhere to and ensure happens every time. Other wise you will break drive lines due to mechanical failures. Lose a couple $30 or $50 props and it will become engrained. Comes with experience.
