Reply To: Changing an imported form

I have installed an SMTP program and the emails are sending which is something but the form is not working on mobile. It displays only the first part of the form and is greyed out .. see screenshot. Please dont worry about the other things that you cant fix but this is important.

Please advise urgently. I hope I dont lose the client because of this. Perhaps you could also let me know why the form sometimes comes up with the error message when selecting some time slots?
