I'm creating a workflow which needs to update some fields so I've added the "Update Record" action. When I set the properties, it brings up the incorrect form to the one which is currently published.
Strangely, it also seems to be missing several fields even under the "Additional Fields" section. Below are the fields I am trying to update:

These are all the relevant address fields in the "Update Record" section:

As you can see, none of them appear to match. How can I force the workflow to either show ALL the available fields, or just the proper Form which is the one I'm currently using?
Thanks in advance for your help.
