arcpy - Two fields have same name in attribute table and not possible to get unique values?

I have run multiple processes in arcpy: convert rasters to feature classes, overlay multiple feature classes and intersect layers. I would like to keep all attributes of my data.

However, I've ended up with attribute table, which contain two fields with the same alias: gridcode (as I have converted two rasters to shp and overlaying them). The field names are actually different (gridcode and gridcode_1).

When I try to display my final map, the Symbology in Layer properties reads only gridcode values of one field. Or course, it is not the one I would like to visualize.

Did you experience not redible symbology? is it because of the same name of my fields? if yes, how can I avoid it? I tried to:

• open the new .mxd document and load data,


• copy my files to new database and load data,


• 
  

  qualify my field names in the arcpy environment settings

  
  

  arcpy.env.qualifiedFieldNames = False

  
  

All without success in ArcGIS 10.4.

Here is some illustration of the same field names with different values (originated from different rasters):

In Layer Properties -> Symbology I can read only the values of the second field...

If I run print [f.name for f in arcpy.ListFields("iBuffSmkGFW")] I've got back:
