BUG? New Key Sequencer visualizer

Could it be that the Key Sequencer visualizer has introduced a bug?

When the Key Sequencer window is open, all keys should be recorded. Sometimes, however, no keys are recorded at all. In that case, I have to restart BTT. This seems to affect editing existing KS in particular.

In any case, I’ve never experienced this before.

And I can no longer edit these values directly (using the keyboard)
