Append a Board to an Existing Design

I’d like to start off by saying that I’m relatively new to Kicad. I created a a schematic and then the PCB. Now, I want to use the Append Board feature to add this Design to itself. When I do this, the net lines all connect between the two boards. Is there anyway to remove these connections?

Just off to show them on the left toolbar.


Thanks, I feel dumb :stuck_out_tongue:
