Hi Jon, it's a temporary glitch as we switch to using the Rockfax grade data when it's available (and current). The crag and climb pages should be showing the correct grade.
The issue is fixed in the development version of the site but we've ended up making some quite significant changes to the logbook section now, so we're waiting for those to be finished and tested before making it live. It shouldn't be long now though.
