I'm really confused, I am converting our DB to Bugzilla mySQL

I prepared flat files (bugs and longdescs),imported files into Bugzilla
(mysqlimport) and then ran "./checksetup.pl" command.
I can see bugs and description through shell and Bug List in UI, but if
I choose certain bug number in UI, it opens the screen which shows only
bug number, but all other boxes are empty.

Any idea what should I pay attention on?

Thanks,
Val
