Odd wear on my rest

nock point to low, just had the same thing raised it up and it stopped.

That wear spot is where your 4:00 position feather is passing the shelf as the arrow starts the archers paradox.  All my personal bows get that wear pattern and have for 20 years.  I minimize this contact by rotating my nock so one feather is at 3:00 (facing into the side plate). Some people call it cock feather in.
This is normal on a properly spined arrow.  The arrow flexes on release and the tail end of the arrow passes 1/4"-3/8" from the side plate.  Search for slow motion videos of the archer's paradox and you will see this.

I will also add that your shelf is wider then it needs to be.  As mentioned earlier you can put a piece of a match stick or leather under the rest that is shorter then the width of the shelf, thus is a sense making your shelf more narrow.  Hope that makes sense.
