Tripping issue with Split load Wylex DB

[ipd1961]

Got an issue at home, today I got home and found one of the RCD's had tripped on my split load Wylex DB.
I tried to reset but it wasn't having it. Switched all MCB's off on the RCD (Call it number 1) that had tripped then reset. All was ok, switched each MCB on and stayed in.
Put the kettle on (which is on the other RCD (call it number 2) and on the kitchen circuit) and it tripped RCD number 1, kettle carried on boiling without an issue to the RCD 2 or the MCB it is on.

House was rewired in 2016 and the new board installed then

HELP, I am at my wits end which is a very short journey

Any ideas will be greatly received. Give me 3 phase any day of the week

They won't know though. Most housing association sparks are lazy as f#€k so will appreciate not having to look at it!!

was it a coincidence ?

is it still ?

Issue was a faulty single socket on the landing

a good landing or a bad landing?
