Until you get your solution:
< &> (next to 0, not the ones next to OK) move through the bouquets. Name of selected bouquet will be presented on the screen. Does it really matter if you don't see which bouquet is next on list?
Press the TV button to open/show the bouquets
Change "show bouquet on launch" to yes so that they are presented to you when you activate the EPG screens.
Also:
The reason you are in the "last scanned" bouquet is that you don't have the Sky info bouquet. As the EPG zapper zapped to that channel, the bouquet it can be found in is the "Last scanned" one.
