A while back I put in a few POI's and mislabelled a couple of them (used a loc dot instead of a quest update dot, etc.). I tried using the edit POI function to remove or change the bad ones and it wouldn't work. When I asked about it on the forums I was told it had been disabled intentionally for security reasons. Not sure if this is what your referring to but if/so it's not a matter of coding, it's just disabled for whatever reason.
The thread I'm referring to is here:
