Copy Bug in Automation Envelope?

Hi,

it seems I’m encountering a bug in Automation Envelopes when I copy envelopes.

When using Envelope Type “Lines” selecting, copying and pasting works fine:
Lines

But when I use Envelope Type “Points” the last point is missing after paste:
Points

So I have to make the selection area one step further/behind the last point in the grid to get all points till the last one copied/pasted:
Points - copy is working

Could someone please explain this behaviour to me or is this a bug?

Many thanks
Denny
