MAC Editor errors???

[Mahalo]

I am wondering if there are bugs in the MAC editor, anyone else found that?

ARP edit. Prog Keyboard 004 Suitcase (actually a copy I made at User126)

The original ARP is a slow riff KEY EPiano Calm, made a copy at User067 (INT)

I added to the end of the riff, it plays them but ultra gated Staccato, whatever i set the length to. Legato, 100%, probably stays on the default short gate so I presume the editor is faulty. Here is the thing - I found it CAN play those notes legato when set legato but only if you switch OFF KEYSYNC and then play a different chord mid bar, then the new notes come out LEGATO. Otherwise Gated Staccato.

That would be a software bug - editor on CD in the box bought last week in Auckland NZ.

On MacBook Air brand new latest everything but possibly I need to upgrade the editor, it is already fixed? Let me check that too.. but how? New to Mac, how to upgrade or check for a new software for the Korg microSTATION editor, and is this bug fixed or not.
