How do you add button for Filters in the Build an App in Mendix Studio tutorial?

There does not appear to be an option to “Add” as indicated in the tutorial: In the screenshot above it has an “Add” button but when I tried it out I only get save?: How do I add a filter button?

This is probably an issue in the documentation and the Add button was available in previous versions and is now a Save button.
