I have a two 32mcb in the c/u. I thought one would be for the upstairs sockets and one would be for the downstairs sockets but they are not.

both require switching off to cut off power off to both upstairs and downstairs sockets!! is something wrong with this?

each 32mcb has only one live exiting, surely you cant have a ring circuit from one mcb to another, it should exit and return to the same mcb, shouldn't it?

Unfortunately this is quite common. Suggest you get a spark into check and resolve

Have you carried out any dead testing on the two circuits in question r1, r2 or rn? What size cables are the CBs feeding?

I did an EICR on a large house last year .......... all the 32A breakers had 2 cores ............ unfortunately, none of them were paired correctly :(

get an electrician in to see what is going on, from first appearances, this is both wrong and under overload conditions could be potentially dangerous.

Sometimes you will get legs going to feed upstairs then en route they drop down in a chase to downstairs sockets.
Best way is with a plug in tester, switch one MCB off and mark which sockets are off with that one, then do the same with the other.
Mark it on the socket or on an A4 sheet and stick it with the consumer unit.
It’s the way it is sometimes.

Was going to a second time but hit the back button instead - foot of stairs!
I’d be right in a parallel universe though!
And you can't get away with editing a post once its been quoted either!
