We had this exact issue too. The answer was to modify the workflow. Select the transition that currently isnt resolving (in our case it was transitioning from "In Review" to "Done") and adding a new "Post Function" which updates the issue field "Resolution" to "Resolved". After that all the little graphs etc were correct. You can also bulk modify issues that are unresolved by transitioning them to "In Review" and bulk updating them again back to "Done" which then correctly set the resolution field. Unfortunately this technique means that all your issues are now resolved on the same day so your graphs etc show a big spike on one day. For some reason this bug occurs after a few days with any of the default workflows in Jira, but it's not too big a deal if you spot it early and fix the workflow to resolve issues correctly. As for the Jira/Godzilla thing, I always thought it was a reference to Mozillas Bugzilla, which I thought was kinda cool :) Hope that helps!
