Low Search - option thats not in field being searched for

Question

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?

http://mydomainname.com/index.php/properties?search:property_address_set:address_ward=Select+option

<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>

You need to add value="" to the first option. This is how HTML and forms work.

• This <option>Hello World</option> will submit Hello world
• This <option value="hi">Hello World</option> will submit hi
• This <option value="">Hello World</option> will submit an empty string
