Why are members showing "INACTIVE" when the inactive membership field isn't selected?

You may notice that even if you've manually amended the Approval status to "Yes" and the Inactive Membership drop down isn't active, the Membership link on the Person Details page displays as (INACTIVE) Member.

This will happen until the Membership is fully activated by running report 259 "New Members to Approve". Once this report has been run and the member's approved status is set at "Yes", they will be ACTIVE members.
