I've had this before on the PLi Jade image, this was for a DM500 but still the same idea.... Only way I found at the time was to manually remove the bouquet files by FTP in the /var/tuxbox/config/enigma/ directory and the satellites.xml file in /var/etc/ then reboot the receiver, then load the news settings again via DBEdit, there is probably an easier way or some reason it keeps the old settings, but this worked for me at the time and not come across it again....
