In a form that I'm building, if someone attempts to erase information from an optional field, the form will display an error that the field is required and not allow the form to submit. I have the field set to optional, but is there a setting on the form level that I'm missing?

<q2-input
            class="q2-col"
            name="address_2"
            id="address_2"
            label="Address 2"
            optional
            oninput="validateInputEvent(event)"
            value="{{ address_2 }}"
	></q2-input>
