Wires are in the wrong terminals.
Both the switch and box is clearly marked L on the left side and N on the right.
Some buffoon has then put the neutrals into the L terminals and line into the N terminals.
A case of two wrongs making a right - until someone then changes the T&E and looks at the markings rather than the incoming wires.
And as all three of those meters are fairly new, is it really so hard to get three of the same make?
