Artifact Dependency Excludes

Hello.

I am looking at http://youtrack.jetbrains.com/issue/TW-16222 and i can't get the artfifact exclude to work properly.  This is how i have it setup:

Build 'A' produces myartfiacts.zip

Build 'B' Uses certain files from myartifacts.zip (from an artifact dependancy), setup like this:

+:myartfiacts.zip!MyPath/Binaries/Platform/**/* => MyPath/Binaries/Platform
-:myartfiacts.zip!/MyPath/Binaries/Platform/DummyDLLs.*

But when we run the build and download the artifacts, DummyDLLs.* still get downloaded!
Are we setting this up incorrectly?  Is this possible to do?  Or do we have to manually list every single file out..?

We are on TC7.0.3.

Thanks!
