Problems with Dynamic Legend in 10.0

[JaneWickers]

We're using the out-of-the-box PrintTask from ArcGIS Server Manager. I've successfully created 3 print tasks (see http://mapping.tweed.nsw.gov.au/planningjw/Default.aspx).

The problem is that sometimes the dynamic legends work and sometimes they don't. Usually the first template selected works, but if you try and print a different one, the dynamic legend stops showing the correct legend. It's like there's some kind of caching problem.

Any ideas?
Thanks.

The code for the Vegetation Map is:
