Layer's symbology polygon info stuck in "all other values" with arcpy

danieloccasionally

I have some arcpy python code that successfully writes the symbology of a layer but the actual polygons only show up as "<all other values>". Any ideas on how to correct this?

The fields data are domain values, I'm not sure if that effects anything.

 

Here's the code:

import arcpy, sys, os
print(TWP)

aprx = arcpy.mp.ArcGISProject("Current")
m = aprx.listMaps("Map")[0]
l = m.listLayers(TWP + "_RIGHTS")[0]
sym = l.symbology
    
sym.updateRenderer('UniqueValueRenderer')
sym.renderer.fields = ['RightsType']

for grp in sym.renderer.groups:
    for itm in grp.items:
        label = itm.label

        if itm.label == "Choose":
            itm.symbol.color = {"RGB": [0, 0, 0, 50]}      
            itm.symbol.outlineColor = {"RGB": [255, 255, 255, 100]}
            itm.symbol.outlineWidth = 0.75
            itm.label = str(label)

        elif itm.label == "Easement":
            itm.symbol.color = {"RGB": [0, 112, 255, 50]}      
            itm.symbol.outlineColor = {"RGB": [255, 255, 255, 100]}
            itm.symbol.outlineWidth = 0.75  
            itm.label = str(label)

        elif itm.label == "Fee":
            itm.symbol.color = {"RGB": [56, 168, 0, 50]}
            itm.symbol.outlineColor = {"RGB": [255, 255, 255, 100]}
            itm.symbol.outlineWidth = 0.75
            itm.label = str(label)

        elif itm.label == "License":
            itm.symbol.color = {"RGB": [255, 0, 0, 50]}
            itm.symbol.outlineColor = {"RGB": [255, 255, 255, 100]}
            itm.symbol.outlineWidth = 0.75
            itm.label = str(label)

        print(label)    
    l.symbology = sym

aprx.save() 
print("Completed"+" "+time.strftime("%x" +" "+ "(%a)" +" "+ "at"+" "+"%I:%M"))

I found that arcpy.da.UpdateCursor causes the polygons' information to be stuck in <all other values> and thus unable to display the symbology. @Anonymous User identified that this is bug.
