Accessibility – Attribute ‘sort_order’ not allowed on element.

Hello,

We are currently doing accessibility checks on our website and have had the accessility error “Attribute ‘sort_order’ not allowed on element” flagged.

The fields we are having problems with are <span class="wpp_sortable_link label label-info" sort_order="DESC" sort_slug="number_of_bedrooms">.

Would you be able to add the appropriate text for the span please?

Thank you.
