Locked out of my own model Geolocation

I have Web-based SketchUp Shop.

I went to do shadow studies on the most recent FLW house model that I had created. They were all misoriented. Somehow, North had been moved to West. This is a model that I had Geo-located to its original historic location.

When I went to correct its location, I found that someone had locked their own incorrect Geolocation in on my model and I was unable to correct this. I consider this a severe bug in the program. I have an unalterable wrong location, 2000 miles away wrong, with model North facing West, and I can neither delete it or reinstall my original historically-correct location.

Mr. Wright designed his houses in sympathy with sun and shade. My model is now out of sync with his intentions.

Only the creator of a model should be able to unalterably lock in a GeoLocation.

Help!
