Custom Maps in My Collection

If I have custom maps in My Collection in BaseCamp I receive a BaseCamp Initialization message when the program starts. "Cannot load following areas: KML Data". I select "fix", basecamp opens and all is well including the custom maps. It doesn't matter if the device is connected to the computer or not.

If I delete the custom maps from My Collection, I do not receive this message and do not see the custom maps unless the device is connected.
