GA4 Midi Pattern not Completely Shown


When I import a MIDI pattern using the “Pattern Library” in the Agent, the pattern is not shown completely,
although the corresponding keys are moving (virtual keyboard)
And with the existing content, no patterns show up at all, and when i try to edit the pattern stops working and only the edited hits work.

Is this correct?
If yes, what is the function of the pattern editor when i can’t see the patterns and edit existing ones?
