Qualtrics Survey has broken submission field

The current version of the survey you get from in game asks at some point: "What is your summoner level in League of Legends (or highest level, if you have multiple accounts)?" It keeps giving me an error above that question when I try to submit the page that says: "Please enter a valid number." I've entered both basic numbers and roman numerals for the "number" ...nothing seems valid. I think someone forgot to create the input that validates if a number is a number... So, I guess I won't complete the survey, though I think I was probably very close to done.
