[Theme Horse Support Team]

Hi Guilherme,
If you have not changed any custom code then follow the theme instruction first how to set up the gallery page. Its working fine in our demo site so it must work in your site too. I think you are not following the proper guidelines or there may also be some plugin conflict. Due to this it is not showing properly. You can even view in our demo site and its working fine. If there works fine then in your theme too it must work fine.

Thank you!
