When markAsMembersNeeded is set to false, it should set # needed to zero.
When markAsMembersNeeded is set to false, the input disappears and if there was an erroneous value beyond the yup constraints, the form will give a validation error but the user can't see where it is. Remove this validation when markAsMembersNeeded is false.
