[SOLVED] - Version history - great feature, but all I see is a huge empty window

The newly introduced version history is a great feature! But - what is the purpose of this huge empty window?

UPDATE: Ok, I've learned we should see the saved versions of notes in this window. But not a single version shows up here (web client on Firefox and Chrome on macOS).
Unfortunately, at the moment the only effect the new feature seems to have is that Nimbus has now become slower again.
