Any Yahoo Groups experts out there???

To make a long story short, I belong to a few groups and all the events on the group calendars are showing up on my personal Yahoo calendar and I want them off!
I can't seem to get them off and everyone I ask doesn't seem to have a clue either. I've tried changing the settings in the groups (I'm even the owner of one group so I have full control) and that didn't work, tried the settings in my personal calendar and that didn't work, and I even emailed Yahoo and who knows if I'll ever hear back from them!! Any ideas?
Thanks!
