I know exactly what you mean!!
I updated my dreambox to 4.31 and suddenly 5.0e and 1w dissapeared from my sats!
So I read on gemini forum that they have changed 5.0e to 4.8e and 1w to 0.8w.
1w scanned in ok at 0.8w, but when I scanned 4.8e I couldn't even get INTER and ENTER (bloody strong signal)
So after messing around with it for a about 3 hours I gave up flashed my dreambox back to 4.20 (where it is still 5e & 1w) and signal came in nice and strong on 5e.
Moral of the story:
If it ain't broke, don't fix it!!
