A few days ago (it seems) Time Entry appeared on our all of our forms. We don't track time on any of our issue types and I would like to disable it. I don't want it on the forms.
My research showed I should simply go to Settings-> Field Configurations -> Issue Features -> Time Tracking and click the button to disable it. Only problem is, there is no Disable button!

I also tried hiding the Time Tracking field in Field Configurations.
I have spent all day researching and still no solution. What am I missing?!
