Pro Version 2.6.2 not maintaining fully qualified field names during intersect - even though box is checked
I am Intersecting three feature classes, two of which - LZN_20200702 and LZN_20210630 - have the same field names.
I have ticked the “Fields > Maintain fully qualified field names” but the output is only labelling the FID for each feature class, and not maintaining qualified field names. I need to know which original feature class the field "SYM_CODE" is from to enable a definition query.
Have I missed something ?
Screenshots of the dialog boxes:
1. The intersect feature Parameter settings

2. Environment settings

3. Resulting fields

Thank you!
