Hi Joël,

As Dino mentioned, buses in KiCad work just like net labels:  Another
bus with the same name on the same schematic sheet will be connected,
the same way that two pins will be connected if you place the same net
label on them (even if you don't draw a wire between the pins).

If you send me your whole schematic instead of just the PDF I can take
a look to see if there is any bad behavior going on, since bus
behavior did have lots of changes in the nightlies.

Best,
Jon
