The problem is picture 4.
Split legs. Terminal 2 and 5 should be blue/white to 2 and white/blue to 5. You have split pairs here. Sack the electrician.
Where you have colour code blue/orange green/brown its blue 2 orange 5. and green 3
Where you have colour code blue/white white/blue its blue white 2 and white blue 5 and orange white 3.
You have totally split wiring and also will need to regularise at the junction boxes cos just rejigging the sockets wont work.
colour codes should be regularised as follows. Join wires in junction boxes and sockets according to the colour codes of the cables. .
Blue/white = Blue = Terminal 2
White/Blue = Orange = Terminal 5
Orange/White = Green = Terminal 3.
