Nuendo 10.3 Where is the record button in the key editor?

There used to be a record button in the key editor that would allow to record midi regardless of the record button in the project window.
I can’t find it anymore. Is it gone or am I missing something?

Upper left-hand side of Key Editor window between Solo Editor and Insert MIDI Retrospective Recording in Editor buttons.

That is where it should be, but it’s not. See picture.

Make sure you have Default Items ticked in the Toolbar setup in the Key Editor. (Right click next to where the Record Button should be) Do that and it should present itself.

That was ist. Thanks a lot.
Labelling of this could be a bit more precise. I thought this was to reset the items to a default state.

Weird that it was gone after the update to 10.3…
