Multiple net labels ERC warning doesn't display net names for component pins
Eeschema ERC is giving me the error attached. I don't get this error with version 5.1.5 using the same project. (Schematic can be loaded into either version, although the board file cannot be.) Eeschema 5.1.5 reports no errors correctly.
The schematic is a single sheet. It is 12 years old, and has survived multiple manufacturing runs and multiple versions of KiCad. Obviously the error messages are rubbish if for no other reason than that two names are not given. It is not a PWR_FLAG issue, as both GND and V3.3 have their own PWR_FLAG. The problem moves if you rerun some wires, but it is always two error messages saying the same basic problem.
Also attached is the PWR_FLAG graphics. You can see that the GND net is indeed also named GND_, but V3.3 has no second name.
