Problem with group_connector option

[dilydaly1]

I had 2 connectors on my board, which were different (both footprint and value) but KiBOM tried to combine them and joined everything together.
I changed group_connector to 0 and this fixed it, but it clearly doesn't work as it is supposed to with group_connector=1

@dilydaly1 can you provide a simple minimum working example schematic?
