The reason why the "Enter a valid e-mail address" is showing in your "Briefly explain your situation" field is because the validation type on it is set to "E-mail".
See screenshot below. You'll need to change it to "none" if you want to add free text on that input field.
I hope that helps. Do let us know if you need more information on this.
