This issue occurs when multiple versions of Hallmark Card Studio are installed on the computer at the same time. For some reason, something becomes cross-linked between multiple versions and the various versions' Event Planners. So, for example, when you are in Hallmark Card Studio 2007 and click on the multiple addresses option, it may be pulling the information from Hallmark Card Studio 2005's Event Planner.

Unfortunately, the only solution to this issue is to uninstall all versions of Hallmark Card Studio and Event Planner from the computer. Then, reinstall the one version of Hallmark Card Studio you wish to work with. If you reinstall multiple versions, you may develop this problem once more.
