[Xymon] .default. host and CLASS and NOPROP tags

I'd like to use the CLASS and NOPROP tags in the .default. hosts entry, it doesn't seem to be working for me. Can anyone confirm if they have this working for them? or if I've made an obvious mistake?

0.0.0.0 .default. # CLASS:group1 NOPROPRED=disk 1.2.3.4 server1.example.com #

The man page says both of these tags should work, and I've gotten others to work like TRENDS and HIDEHTTP, just running into issues with CLASS and NOPROP*

I'm running Xymon: 4.3 RC1 though I tested the same settings on 4.2.x and it doesn't work there either.

Thanks
