I've set up a sprint with "Original Time Estimate" as the estimation statistic, and set the time tracking to "Remaining Estimate and Time Spent". When I log work or reduce the remaining by editing the ticket, the change is represented, but I can't do this by clicking anywhere on the card. The documentation (https://confluence.atlassian.com/display/GH/Estimating+an+Issue) states "Enter the Remaining Estimate for each issue by clicking the Remaining field on the right-hand side of the card", but this doesn't work. No matter where I click, I am unable to actually change the remaining estimate.
Edit: I'm using Greenhopper 6.0.8 with Jira 5.2
