Exporting bindings to Orchard 1.6

I'm having trouble exporting (via the export module) a binding I created in the Bindings tab of the Query page, has anyone encountered this before?

I tried first on my project that I am working on, when that didn't work I installed a clean install of Orchard and tried it there. However, the binding still does not show up in the exported xml, the request I created pointing to the binding comes out ok and still points to the type.

I checked in the error log but there is nothing there ...

Any thoughts or advice is appreciated.
