BTW do upgrade ot the latest 8.0.x, it will not affect your configuration and may fix bugs.

Start from upgrading to latest V8 version.
I moved from V7 to V8 when V8 reached 8.0.3, so I have never used 8.0.1. It is because typically first new main version releases have many bugs. Each last digit version number change means several dozen bugs fixed.

What should I do?

After you are finished with upgrading you should put on a record and listen to your favorit music. Afterwards you open kicad schematic–>File–>Schematic Setup–>project–>bus alias definitions and carefully look through the “Alias” column. You will find two rows with different definitions for “CB18”. Delete one.

PS: very helpful to attach the project directly in your opening post! (imagine thumbs up icon here)

That does it! Why didn’t I tink of looking there.
Many thanks

Is this the place to ask for the ERC to check for duplicate alias names?
