Pidgin pushbullet not syncing

[DoctorSubtilis]

While Firefox pushbullet is syncing with the phone, Pidgin pushbullet does not sync: even I delete a contact or change a number contact I get always the old values. EDIT nothing to do even seaching all the /home that numebr: it come back always! EDIT noting to do in a new installation on new pc, always the bad number come back; so cleaned phone cache (contacts and telephone). Nothing to do: always the bad number come back.
