Performing a Global Parameters reset on the HD500 does not change any presets but it does restore the Setlist Names to the factory defaults. I think what has happened in your case is this sequence of events:

1) You updated the device firmware to v1.43 and chose to keep your existing presets. This resulted in the factory Setlist Names for 1.43 to be downloaded into your device, but not yet used/visible because you kept the existing ones. However, the device now knows that v1.43 added a new factory setlist (BASS/ACO/VOCAL) in setlist #4, adjusting the Setlist Names accordingly, meaning the User1 setlist name is now in setlist #6 while setlist name #5 is noe L6Link<-> DT. But I repeat - none of this is yet visible because you kept your existing presets.

2) You performed a GLobal Parameters rest, which now updates the Setlist Names (but only the names - the presets themselves are not affected). Now you have the confusing situation you describe. The setlist named USER1 (now in position #6) does not correspond to the presets that are contained in that setlist. After the panic has subsided, you find them in setlist #5 - which is now named L6Link<-> DT. And, of course, the setlist labelled BASS/ACO/VOCAL does not contain any BASS, ACOUSTIC or VOCAL patches. Instead, it contains whatever presets you had in setlist #4 when you performed the firmware update and chose to keep those presets.

3) The resulting situation is that your HD device setlist names now show the factory names, but the actual presets do not correspond because you have not actually updated the presets.

To synchronize the setlist names with the presetsyou can either:

a) update the firmware again and this time choose not to keep your existing presets. Of course, you should back up any setlists/presets you want to kepp before doing this.

b) use the HD device editor to rename your setlists so that they reflect the contained presets. Don't forget to hit the Enter key after renaming the setlist to make it stick. The SEND SETLIST to the HD device - this will update the setlist name.

Hope this helps.
