Virtual tour is not showing on the MLS

There are three fields within the Virtual Tour Information section in Add/Edit- two are for unbranded tours and one is for the branded version:

The URL that is added to the unbranded field(s) (Primary Virtual Tour URL and Additional Virtual Tour URL) will show on the MLS; the Branded Virtual Tour URL field is for IDX (agent and brokerage) sites.

If you add the tour to the Branded field only, it will not show on the MLS
