Default Data Center unchanged after transfer.

After transferring my character from Adamantoise (Aether Data Center) to Tonberry (Elemental Data Center), my default data center is still set to Aether because I have an existing character that I'd like to keep on Adamantoise. Every single time I log out of my Tonberry character and log back in, Aether is still my starred (default) data center.

I sent a support email, and all I got was:
"We understand that you are experiencing difficulty with in-game content and we apologize for any inconvenience this may have caused. Based on your description of the concern, we would like to draw your attention to the Active Help directory in the System Menu. Each time you encounter a new aspect of the game, an entry is created here to explain any helpful details and reviewing these entries may be of great assistance to you."
There isn't anything to do with this in the active help menu.

Is there any way to change the default data center without deleting the character?
