Hi RicRob,
Are you sure you are actually SAVING your changes? To actually save (or write over an existing) User style you must go to:
Function>DigitalRecording>Style Creator>Assembly Tab>Save
Also, a style can ONLY be saved to the User Memory Style Section, not directly to a floppy. You can later copy/paste a style from the User Style Section to a floppy though.
Hope this helps.
