Data Card Deleting Custom Properties

We've had a bizarre issue in the last two days with PDM. When we enter data in the data card there are a number of custom properties that are being deleted.

Two examples.

Enter Eng Date and the Finish was being deleted.

Enter or change an 'approver' and the description is being deleted.

In each case it appears that the last field listed in the custom properties is being deleted. Anyone else see something like this??

We are running SW 2009 and PDM 2009
