I think that you might have the wrong chainring offset for the current frame.
From my knowledge a 55mm chainline needs a 0mm offset chainring or a couple crankset spacers. So using a 3mm offset chainring might be what is causing your shifting issues and interference with the chain stays.
Wolf tooth has a pretty good article about 55mm offset below.
