You should be knowing that "iOS 8.1" has not been added to the dropdown list there yet.
BTW, if you have a real bug, and not just a gripe, I'd use bugreport.apple.com where you can submit a real full report and have a conversation with developers. I'm currently in the middle of one about keyboard shortcuts not working (yes, even after deleting and re-creating them...) and they want me to send stackdumps, and the like. I'm happy to help if it fixes it or gets it figures out.
The feedback link is more for suggestions, I believe...
