2016 Grizzly Shifter problem

Ok guys need your help,
My wonderful 26 year old daughter took our Grizzly for a ride. Had her boyfriend and sure there was some showing off involved in this ride. Well when I got the grizz back the shiftier does not work the way it is suppose to. NONE of the gears line up with there slot that they are suppose to be in. Neutral is Reverse, Reverse is Park none of it seams to lock into any position. Is this an adjustment or should I be looking into the lever or into the gears shift forks? Grizzly has 560 mi. Just had the oil changed. I mean just change, tires hit the round and she was gone.
