this problem occurred with the direct access to the ROM data above bank 3 - which was the normal way I accessed the data (perhaps not part of E-mu testing)
So I added a second method to access these patches (or any ROM Bank patches).
There is a radio box two thirds down, to the left of the patch list called "Method" .
The options are how the program requests the patches, either directly from the ROM or calling each of the ROM's patches into the synth's edit buffer and then getting the edit buffer (doesn't take much longer to do).
Let me know if you work out another way to directly get the extended banks from ROM so I can add it to EmuLib.
All the best
