How to force direction of a connection from a magnet?


I’m trying to draw a local network and I want all connections from the PCs to arrive vertically to the switch’s magnets. But two of them refuse to be vertical and arrive horizontally (left). How can I force them to become vertical like the others? Moving the line’s handle makes it even worse (right):

Adding midpoints didn’t help either. The switch is a regular stencil with manually added magnets.

Any help or hint is highly appreciated.
