Why do DINTIS and DINTOS objects cause workplace to crash when code is generated in Function Designer?

I am integrating a Profibus device into 800xA 5.1 RU1k system. The project is using AC800M controllers (PM866) and CI854A Profibus masters. I can add DINTIS and DINTOS objects to a function diagram with dummy names and have the configuration generated properly. However, when I assign the proper IO names and descriptions and insert the signals into the Control Structure, generating configuration causes the Engineering Workplace to crash.

I need a workaround for this. Installing rollups or TC's is not in my scope and may not be permitted by the customer or engineering firm.
