Where saves Audya one style that's into a SINGLE REGISTRATION?

I have a doubt, if you save one SINGLE REGISTRATION with a style into the REGISTRATION, and after you put this SINGLE REGISTRATION in other Audya, the style isn't in the folders of STYLE, but the style works, OK.

The problem is that I load this SINGLE REGISTRATION, (with a style into) and after I edit the style with the VIEW and after I save the style, and write a new name at the style, when I SAVE the style the light of the DISK HD blink, but I don't find never this style into de AUDYA, (I search the new name of the style but don't find it)

I can't edit the style in the EDIT of the styles 'cause to make this is necessary search the style from the list of the styles, USER STYLES or PRESET STYLES.

Anybody knows how to recover the style from the SINGLE REGISTRATION?

Regards.
