Help with Tuneomatic Bridge

Just recently built up my first kit. It’s an RD-1 and turned out pretty decent and plays great. One bridge post fit snug and correctly. The other is quite the opposite. After a bit of tuning and playing, the said post begins to work itself out of the hole. Tried wrapping tape around it to bulk the post, but doesn’t help. Any ideas?

For an easy fix I'd be tempted to just glue it in with some epoxy. The more correct method would be to fill the hole with glued-in dowel, then drill it out to the correct size (diameter of the insert not including the fins).
