This is the expected behaviour.
Events are processed in order - A, B, C, D
So when your aux B is processed, the track is configured to repeat the
current note 3 times with the desired offset.
When aux C is processed, aux B has already been processed, so masking it has
no effect.
That's why there are no events to mask aux A - they would never take effect.
It's good practice to start with aux C or D for events, then masks can be
added 'in front' of them later if you want to.

A new v4 build is imminent, which fixes a few things, and adds some more
features.
Anyone else using it ?
I've not had much feedback...
