The QAD on my answer was the same way. If it tunes and shoots fine I wouldnt worry about it.

Id recommend the spacer that come with rest if you still have it, if you are questioning it might as well fix it right. If you don't use the spacer you will not get total fletching clearance, I have experienced this first hand.
Bows come and go....
The spacer will center things up by moving the launcher arm back under the containment bar. Definitely will give you a cleaner look.
