I know a lot of folks are unhappy about their stats not matching up with finds on GC.com
I'm still working on the assumption that GS will resolve it with a new type and count em. But, if this is one of those things you really hate, I believe there is a way to get rid of the Lab Caches you've logged.
Groundspeak is now allowing Lab Cache logs to be deleted by doing the following:
Go to: labs.geocaching.com
Log in using your Geocaching Lab credentials.
There is an innocent looking down arrow on the upper right of the screen. Click on it.
Click on "View Your Logs"
Your logs will appear with a trash can icon on the right side. Click and away they go......It is however un-reversible....So be sure this is what you want to do!
