Altium net has only one pin in hierarchical design despite port connection
You did repeet the scheets but not the sheet entries.
Repeat(COUT, 1,5)
By this you have the components from this sheet five times.
when you name the Sheet entry SENSE the SENSE port of all fife scheets are connected to the identical net. (sometimes this is intended)
Leave the port name of the sub sheet named SENSE but on the sheet symbol with the repeat statement you need the call it repeat(SENSE)
you need to name the net between the repeated sheet port and the bus with a net label called SENSE
