Apologies if this is a simple question, but I'm relatively new to Inkscape and have been trying to figure this out for a while...

I'm trying to get rid of the straight line stretching from the top of the image to the bottom. Ideally I'd just like to break the path between the two nodes at the base and those at the bottom, but when I hit 'break path at selected nodes' it does this

Making the two additional lines about the nodes.
Thank you for your help!
