[Analog6 (Odille)]

I have long had the problem that the downloaded elements such as comets didn't show on my screen. When I searched it would go to the area but no handles or anything.

So yesterday I deleted Stellarium and uploaded a new version (I have an iMac running 10.6.8) and it now seems to find them but on every comet I search for it goes to the same place and finds an object with the label Atlas Centaur 2.

Suggestions? Are there settings I need to make different?
