Hi,
F.Y.I
One of the wall lights is on the same wall as the switch, but the other wall light is
on the opposite wall.
I have relooked at the ceiling rose, as can be seen below.
From the looks of things the yellow wire is acting as a 'switched live' sharing the same
cable (the white one on the left in the above image), as the ceiling light.
Then once it gets into the ceiling rose, it is split out and then feeds power to blackish grey cable
(on the right),for the wall light on the opposite wall. Would you concur?
Therefore, it may be that the yellow wire in the switch is not making proper contact and
maybe the reason for the opposite wall light not coming on.
Also, in my original diagram I had not shown the earth from the white cable, but on
further examination, I think the earth wires have been paired up in two green sleeves,
so I have added the missing earth to my diagram below.
