wlan0 persisting network

[alive2]

This worked out of the box for me for RPI4, I'm hoping to get guidance on 2 problems I'm facing;

1. Once connected to a network I can't seem to undo it, is it possible to "forget network" with the API (I was hoping that this would solve problem num.2)?
2. When I attempt to connect to a different network, it doesn't seem to want to let go of the old one. Sometimes I even see the wlan0 ipv4 address jumping back and forth between the 2 networks although it seems to persist with the network that it was already connected to.

Thanks in advance!
