I found a post describing what I’m experiencing, but it is marked as solved:
https://community.skuid.com/t/picklist-field-showing-old-values-field-dependencies-not-wo…

We’ve overhauled the dependent picklist options in one of our processes, and the options are not updating in Skuid.  I’ve tried deleting the field from the model and putting it back.  I’ve tested with a new page creating a model with just the fields involved in the dependency.  Only seeing the old options.
