I'm trying to reproduce the problem, but am not able to. The Selected column is being added to the session variables list.
perhaps try deleting the Dreamweaver cache file from the users configuration folder:
common_installation_issues.pdf
in the mean time, you can manually edit the code.
change:
"sessionColumns" => explode($WA_Auth_Separator,"memberID"),
"sessionNames" => explode($WA_Auth_Separator,"memberID"),
to:
"sessionColumns" => explode($WA_Auth_Separator,"memberID".$WA_Auth_Separator."memberStatus"),
"sessionNames" => explode($WA_Auth_Separator,"memberID".$WA_Auth_Separator."memberStatus"),
