What do you mean?
Not trying to make you sound stupid or anything, but you have noticed the three bars in the "sandwich" button to reveal the amps and cabs?
The cabs and amps aren't there? What IS there? I installed my XT purchaces and the now legacy XT stuff, and it looks something like this...
After expanding (Notice that's an amp from the XT collection?):
Tried re-installing the content?
Or am I missing the point all together??
