It sounds like more of a stock fitting problem if the single trigger works just fine with the stock off. The alignment of the receiver body with the floor plate is critical for proper sear/trigger alignment. There are 2 long screws that go through the stock to secure the receiver to the floor plate. The big screw under the top lever that screws into the floor plate and the smaller long screw that goes through the floor plate and screws into the top tang, both go through holes in the stock. Over or under tightening of these screws could change the relationship of the triggers to the sears. Hope this helps.
