Tvheadend

i've an hauppauge nova-td-stick with two tuners and tvheadend recognize it as DiBcom 7000PC, so i select as muxes italy and i wait until "Muxes awaiting initial scan" is 0
but when it's reached 0 "map dvb services..." is greyed out, and in the log i've this:
Feb 16 10:18:47 uk_freesat: install table handlers
why? i've set italian not uk...
