Hello Bertrand,

It seams the same as:

https://gitlab.com/kicad/code/kicad/-/issues/3460
	"bus members with the same name are merged (lp:#1830233)"

the answer was:
" This is expected behavior.  Group buses are not namespaced unless you 
add a
name to the group.

If you want to have two different nets, you need to add a name to the bus
definition, like `BUS1{ASDF}` to get nets like `BUS1.A`
"

Did you use the tools->bus definition to define the bus type?

Cheers,
