i went back to the shop and he said there is a simple fix. he said if i loosen the two screws holding the sts system in place and turn the end a little so that it is further to the right(side it is slipping off of) and then retighten the screws it will fix the problem. this would simply move the rubber end to the right so that it cant slip off the right side anymore. do yall see any downsides to this suggestion?

another question, do i need the string to be touching the sts when the bow isnt drawn, or should there be a little gap of space in between?
