Norsky is correct on the adjustment. Also, if the pegs a worn, turn them out 90 degrees and get the spring loaded clips to contact a portion of the pins that aren't worn. If they are worn all the way around, they may need to be replaced. Once they are latched, they really shouldn't "pop out" at all.

Excellent advice from Norsky and MikeMc. Glad it worked out.
