WAD: Inhibit Export Text Web Item

There is a Text-Web-Item in our Template which is not bound in the export command.

That´s why this Text-Web-Item was never exported in the past.

Now we´ve made a upgrade from SAP BW 7.0 to SAP BW 7.31.

And now the same Text-Web-Item will be exported (even though it is still not bounded in the export command).

We´ve found out that this problem (under SAP BW 7.31) only exists if a Text-Web-Item is inside a container.

Text-Web-Items that are outside of a container still won´t be exported.

Any ideas how to prevent this Item from export?
