I have imported email addresses and they exist and with the correct email address. But do not show up in the proper column in the listing. IE: the email address only shows after I click the name, then it shows below the dialog box. The fields are almost all blank but some info is there.
Fields are blank but information under the window is correct.

I'm new to Thunderbird and have lots to learn. Nickname is a column I use to collect like groups.
I believe I had some wrong titles for the various columns when I did the import from a .csv file. I fixed the header/titles and it seems ok for now.
