Kent,
I reported a similar problem in April.

I am editing some of my old MIDI styles to use RealTracks, using the StyleMaker. It seems a very easy process, as I just load the RealTrack name under the Miscellaneous / More buttons.
However I cannot get a new Long Name to replace the old data. Similarly I cannot find any way to modify the information (eg No Memo found and the instrument list) that appears under the style name in the chord sheet. Any text I add through the action button / custom memo just gets appended to the Memo function.
The data that is shown seems to be from the old MIDI style, rather than the updated Real style, and is now incorrect.
