membership breaks genesis widgets?

I’m trying to get Membership configured on a new blog that is using the Genesis Framework and a StudioPress Child Theme. I’m using a couple of Genesis Widgets and they don’t work correctly with Membership enabled.

The first one I noticed not working correctly is Genesis Featured Post widget. The other is a similar widget, its the Genesis Featured Post Grid widget.

Both are configured to limit the display of posts according to post Category. I have 3 posts in Cat A and 2 posts in Cat B. But the Grid widget shows only 2 of the 3 Cat A posts and the other widget shows posts from Cat A, B and C.

If I disable Membership, the Genesis widgets work correctly.

Any ideas or suggestions?
