Evohome override in multi room zone

We have one zone which is actually three rooms, a downstairs wc, utility and small hall connecting the two. One radiator in each.

Previously this was just set as a single room with three rads. Primary HR92 was the one in the hall, theory being if that area is up to temp then the other two will be.

We were previously able to override the temperature in the utility room to say 24 degrees and it would alter the temp of the other radiators (expected) and also revert back to the setpoint 5 degrees at midnight (so any manual override would be cancelled at midnight if we forgot to turn it back down manually)

I have now changed this to a multi room zone in an effort to be a bit more efficient.

However now if the radiator in the utility is manually changed to say 24, while I see the expected behaviour of the other two radiators not changing, it also does not revert back to 5 degrees at midnight. The manual override stops on indefinitely.

Is this normal that a manual override in a multi room zone does not get overriden by a schedule? Is there any workaround or setting to prevent this?

Many thanks for any help.
