When I look at my Jira tasks in the Greenhopper Scrum Board, I don't have the option to estimate the issues when the issue types are classified as "bug" or "enhancement". It works fine if I change the issue types to "story". I know that by default the Greenhopper Scrum Issue Type Scheme doesn't include "bug" or "enhancement". However, I went in and added them to that scheme, as shown in the link below:

Everything I see is telling me that I should be able to estimate the issues in Greenhopper with my current set-up. Does anyone have any ideas?
