Weave YAML header doesn't get rendered

I started using Weave recently, and just upgraded to version 0.10.2 from 0.9.4. With this upgrade the YAML header isn’t properly rendered into title-author-date (i.e centred with large fonts). One can see this from the example in the Weave documentation on publishing Publishing to HTML and PDF and looking at FIR_design_plots.html. Is this feature no longer supported or is this a bug?
