@DavidForbuss1 were you adding duplicate layers in your map to work around the lack of support for editing Subtype Group Layers in Field Maps? If so, perhaps you might want to consider changing the composition of your map?
BTW, up next with UN in Field Maps is support for Subtype Group Tables (both viewing in the pop-up and editing in the form). We are planning to add this support in time for the next network management release (ArcGIS Enterprise 12.1).
