Unable to release order base

Hi,

We are trying to release an order base by running the action Rerelease Order Base in OTM6.3.6. But we get the below error when this action is run.

"Unable to propagate from SU to SULines when there are more than one line."

The order base has 5 ship unit lines. Any idea on why this error is being thrown?
