OK, bad form, I am posting two replies in a row--- however.
It seems that importing the database into MapSource may have corrupted a couple of the waypoints. I am in the process of manually opening each waypoint and checking it for accuracy.
I also upgraded MapSource to version 6.12.2 , it uses a newer .gdb file. That is the version I will have on my web site. The upgrade is free for Garmin users and I recommend it.

That said, if you have the older version and want to stay with it, drop me an email and I will save the file off in the older version and send it to you.
