Slightly bigger than the first but close enough
Interesting - I've added the orange trace as seen on the other side and it doesn't hit the switches in the red squares but it looks like it does hit the ones you named, assuming a normal keymap. Surprisingly the only switch on the trace that works is \| which is the worst of many stupid design decisions I've seen on commercial PCBs - why is half of the most important pad in a stab hole?! Whatever, we'll just assume everything is broken and test it. I'm assuming you removed the green bridge that made the keys register wrong, if it was ever soldered...
First confirm the cyan pin is connected to the controller chip by touching a wire between cyan and the green pin of the the known working switch next to it - it should type enter.
Next touch the wire between any of the dead key's orange pins and cyan - this should type the dead key. If it doesn't touch the red end of the diode to cyan and that should. If the diode works but the switch pin doesn't you need to solder a tiny bridge between orange and red to reconnect the diode. Repeat for all three dead switches.
If you've soldered any bridges you can now test those keys - they might work. If you didn't solder any bridges or the keys still don't work you need to reconnect the orange trace by soldering bridges to cyan. Connect one of the magentas to cyan and connect the other magentas together to avoid damaging cyan.
I don't see an LED cluster that could be not working, feel free to mark it and I'll have a look.
