Changing Field Label Position on Portal Entity Form

I am trying to change the Field Label Position on an entity form for my Dynamics 365 Online Portal so that the field name and it's value will show side-by-side. 

ex. Section Properties when editing a form

However, the form will not change if i switch the setting to the 'Side' option. The entity form will only show the 'Top' option no matter what I choose. Is this a problem involving my CRM instance or is the 'Side' option for Field Label Position ignored in the portal? 

Thanks everyone!
