If you are editing the "Describe your reasoning" field, and select the numbers field, if you type any character the focus immediately jumps back to the "Describe your reasoning" field, highlighting all the characters. So if you try to type two characters into the numbers field, it will instantly delete all your reasoning field content (which can be undone, but still I'm guessing not intended)
