Expand button suddenly gone after update?

I’m on the latest version of Dorico 4.

Little expand button is there for “write” mode, as it should be.

The same button was available under “engrave” mode. But is now gone.

It was there, I updated, now it’s gone. Of course I can still cmd+7 to open it, but where did it go? I’ve restarted etc and it is still gone, in case you are wondering.

You posted this same point in this other thread:

There’s no need to double-post: we carefully read and digest every thread. Thanks!
