Membership and recent posts

I’m using a theme called Bangkok press which has got a recent posts widget included which I’d like to use with the Membership plugin.

The widget enables me to select a certain category and then include these into the sidebar. When I view the site as a Membership Admin the correct posts are shown, but when I view the site as a stranger or any other access level it brings in the most recent posts rather than the posts from that category selected. (screenshot shows admin view on left and non admin on right)

I’ve checked to make sure that the category selected is visible to all access levels but it only shows the correct posts when view as admin.

Any ideas on if I need to modify something in the widget or if I can use a different widget to produce the same result.

Thanks in advance
