My Low search form always searches for the first option in the field below (Grid column with value/label pairs) even if none of its options are selected. Can anyone help me with this?

<select name="search:property_address_set:address_ward">
<option>Select option</option>
{exp:low_options:property_address_set}
{if option:group != ''}<optgroup label="{option:group}">{/if}
{options}<option value="{option:value}">{option:label}</option>{/options}
{if option:group != ''}</optgroup>{/if}
{/exp:low_options:property_address_set}
</select>
