Blog ID's suddenly missing after upgrading wpmu to 3.1 from 3.0

I looked and have not found anyone else in the forums with the same issue as I am. I am hoping for a quick fix, trying to avoid having to reinstall wpmu.
when I view all sites in network admin view, I just noticed that the blog id's column is missing.
This is a bit of a pain as I will need to resort to the ID's in time for future work.

I have deleted all the plugins in hopes that was conflicting in some way but to no avail.
I am still missing all blog Id's

can anyone please provide a quick fix, or am I going to have to re install wpmu all over again?

Thanks for your time.
