Comments # on BL Dashboard

What's wrong with the comments count on Dashboard? It's all over the place. The personal blogs all show the right count, but the Dashboard doesn't. Or rather for some posts it's correct, while for others it's totally wrong. For my latest post, it shows 18 comments, when there is only 1. For one of Troy's posts, it shows 4 comments, when there are at least 20. 

Or is it only me who sees this?
