Workaround

In the REST endpoint of the layer (https://services6.arcgis.com/vs0Q5ds549q7lQMm/arcgis/rest/services/FirePreIncidentPlans/FeatureServer/2) under the SUPPTYPE field, there are four entries there - this indicates that in addition to the three coded values on the service at REST (likely how the service was published), there is one more value that is likely added to the list of values through the Data tab.
Publish published a service that originally had a domain with two coded values on a field called Enabled, and the layer symbolizes on that field.
Go into the Data tab and add two more values to the list, then into the Visualization tab to make sure those two new values show up on the symbology field, and save the Visualization.
Now when opening the layer in the map viewer, all 4 values under the legend.
