When entering transactions into a membership dues batch the card will default for the constituent, but when adding the membership from an import the cards do not get defaulted to the "Bill To" constituent.
We're currently evaluating this issue for a fix in a future release.
Steps to Duplicate
1. Go to Administration > Import 2. Start the Membership import process 3. Open the resulting batch, select the imported row, select the Dues tab and click the Membership Cards button There is no membership card data 4. Close that screen and enter a second batch row as the imported row 5. Select the manually entered row once complete, select the Dues tab and click the Membership Cards button Membership cards are listed here when manually entered.
