The custom form field is showing: 如何得知我們 How did you learn about us: #%e5%a6%82%e4%bd%95%e5%be%97%e7%9f%a5%e6%88%91%e5%80%91-how-did-you-know-about-us# These should probably be Chinese characters, but the form field content isn't "how did you know about us" I deleted the form field completely and created a new one to test, however I can't get rid of this existing form field that is creating this issue. It won't go!
