[MapProxy] opacity not working?

List,

Unfortunately I still cannot get transparency to work.

I've created a WMS-service to debug.
I've created a minimal mapproxy config with only the things to get it 
going in it
I've created a viewer to see the result.

If you look at the demo-viewer:
http://178.63.74.185/hosting/demo/show_source.html?layernames=Bedrijventerrein&test=true&opacity=1&url=http://test.tiles.md-kwadraat.nl/mp/service

you see that the overlay is fully opaque. My configuration is attached 
below.

Please help me with tracking down this problem.
Is there anything wrong with my config?
How can I track this problem. I really don't know where to start.

Any help greatly appreciated.

Marco
