"Ask a Question" about themes was a little confusing at first!

When asking about a theme in the “Ask a Question” tab, it ask “Choose a site” when I click “other” I typed in n/a since it was a general theme question; then it went back to telling me to “choose a site from the list or other”. Can we add no site to the list, or allow “other” to not require a site? I had to clear it out and click the “Ask a Question” tab again to get it to accept a different site after I got it wrong the first time.
