Wow, great fixes for the new CC Fastrack turnouts. I only have the older remote ones 13 to be exact with zero issues, but should I get more CC ones, I'll know exactly what to look out for and how to correct it.
To me, it looks like the numb is there as a guide and should be facing down rather than up where it can bind. You solution works (cutting it off), but I thinking that someone installed the part upside down is the issue. Not owning any CC turnouts, this is just a guess, but as long as your fix works, you are good to go.
