Hard to tell.  It could be a problem with your librarian software.  

Suggestions: find someone who has whatever librarian software you 
have.  If it is commercial, go to website, look up knowledge base, 
FAQs, or leave e-mail.  If it is shareware or freeware, try e-mailing 
software designer.  Some of them are very helpful and want to hear 
about bugs in their software.  They may even work with you to improve 
the software.

STOP===>DON'T DO THE FOLLOWING UNTIL YOU HAVE READ WARNINGS

You can do a factory reset from the diagnostics menu. Power up 
holding both cursor buttons down.  In OS 2.0, there are options to: 
Initialize User Data and Initialize Data Except Seq. (among other 
options).

WARNINGS:

SAVE ANYTHING YOU WANT TO SAVE BEFORE INITIALIZING!!!!!!!
(eg, do sysex dump of presets to external sequencer or other 
software; use E-Loader to save patterns and songs)

AS FAR AS I REMEMBER FACTORY LOADED SONGS AND PATTERNS ARE NOT IN ROM 
AND WILL NOT BE RESTORED IF YOU INITIALIZE ALL!!!!!

Hope this helps.
