If you go to the "Categories" button up top on the feedback website and click the feedback category you would like to use, you have trouble posting that feedback.  Below the "Details" section when you give feedback there is a drop down menu called "Topic".  One of the categories is in bold because I already picked it, so when I click on it it doesn't let me submit my feedback.  Instead I have to go to the "Please select a topic" option, then go back to the category I want to post feedback in.
