The back is probably strip-muted, but I'd press on it and the front with my finger while playing the note. With the back duplex, it doesn't have to be the note you're playing--can be pretty far up the scale. Also, plucking the offending string while the damper is seated. Those trichord wedges can have unequal sides.
