It is difficult to tell which aspects of the geometry need correcting without seeing the guitar. The necks on reso guitars are mounted very differently to normal acoustic guitars. The body hangs off the neck, in the same way a banjo is constructed. You may need a neck reset or rather re-fix (which is easier on a reso than a flattop). I can see a gap at the heel on one of the photos. Or you may find that the wedge between the neck stick and fretboard support plate is simply too thick and is lifting the fretboard extension.
If the tech you are seeing tomorrow has not had their hands inside a reso then they could be left scratching their head. I would definitely contact Mule. These are not cheap guitars and I'm sure that they will have a fix for you.
