Wayfinder blank Beta 4 - wayfinder 2.1.1

Hi,

I am currently setting up a multi site website with two different contexts the initial site i made works very well and in the template I am using wayfinder for the menu

[[!Wayfinder? &startId=`0`]]

This works fine as expected, however in my 2nd site context I am also trying to use wayfinder but focused on a folder for the top nav:

[[!Wayfinder? &startId=`17`]]

However when I view the site nothing appear at all, I have tried all sorts clearing site cache, making sure the pages are published / viewable in the menu etc.

Am I missing something or is this a possible bug?

Thanks Aaron
