It is in there with licorice I ended up using an extractor to get it out. Customer service is good I ordered a replacement set and they set 4 pairs.

I am having g major problems with my set screw!. It keeps coming loose and causing g the slide ejector to come loose and causing major jamming issues.the fix for this so far is contact fm and have them ship you another set screw to back the format one up so that the first set screw doesn't move..that's the fix so far...I was wondering the same thing even emailed them pics and asked if was defective or design flaw and they assured me everything was right..let's hope ...
