Can't fast forward with recorded program

[OldTester]

It doesn't seem to work for my box
I hit the fast forward button and it shows +10s but then keeps going back from the beginning.
The box is running with Buzz4 firmware version V20211108

Any idea

Thanks

Updated to Buzz5 and the bug is resolved

Seems the problem is back. I cannot fast forward the recorded video
