Hi Jon - thanks for getting in touch.
The dropdown menu option can be a little tricky. This is because although it’s ‘required’ and there appears to be no way to change this in the Design Your Form box, a way to work around it would be to uncheck the Validation Option called ‘First menu choice is not a valid value’. That way, the user will be able to use the first option which is blank and just leave it in that state when submitting the form even though it is required.
I hope this work around helps. Please let us know if you experience issues with it.
