Hi Whit
Restarting the DataLinq server or changing the connection should clear-out any old cached data. The DataLinq information is sent as a stream so the server has no idea that some of the information has been removed from the panel - from its standpoint, the data just hasn't been changed in a while (which is normal).
For more info, I'd recommend re-posting on the XPression side.
