Field level security doesn't seem to be applying to Skuid users?

We recently changed the field level security of a field on a custom object to “Read Only” for most profiles and when the user is editing a record through a Skuid page they are still able to modify that field.

When we remove their Skuid license and kick them back to the regular Salesforce UI they’re unable to edit it which leads me to believe it’s something we’re doing wrong inside of Skuid.

Thanks!
