Exposed filters return wrong results (no nodes)

I have a couple of views running on a development site at http://bhunted.underdesign.co.uk. The site is currently running 5.8 (will update to 5.9 shortly). I am running the following views-related modules:

Bonus: Panels - 5.x-1.2-alpha2
Views - 5.x-1.6
Views FilterBlock - 5.x-1.x-dev
Views fusion - 5.x-1.x-dev

To solve this problem, I have tried uninstalling all the above modules (except Views of course), but this hasn't made any difference.

OK, here's the problem. On the home-page of this site is an exposed set of filters for a View, put there by using Views Filter. If you visit the homepage and just click Submit, the View shows up the three nodes that match (all profile content-types), no problem. But, if you change any of the filters, for example, change Job Location to London (as that should return 1 node), the View returns no nodes whatsoever.

It doesn't matter what you change the filters to, you always get no nodes returned. The View does return the Empty Text message which, I guess, may suggest that the View is working and the problem lies elsewhere (CCK?), I would appreciate comments and feedback on this.

Here is the Export from the View on the home page.

What am I missing? Why is the View blank?! Please help me as we need to get this site completed and launched.
