Junctions are a bit tricky but you make them by holding down the ALT on the keyboard and clicking on a bendpoint, and that starts a trace that you drag to the pin. As usual grab the junction and move it and all the traces should move - this test doesn’t work for 4 junctions because only 3 move at a time -.
I corrected all the junction and made this circuit, but it’s inconsistent, ie sometimes it latches and needs a reset, sometimes it’s instantaneous. I still have the switch connected to GND pin2, but practically every button press is different. If I cut the wire where the label is, every button press is as expected.
