Session Guitarist Electric sunburst don't play certain chords

Hi guys,

I don't know if it's the right forum to ask, but I'll try.

I've purchased Session Guitarist electric Sunburst. The sound and patterns are just amazing.

But there is one thing that bothers me - I'm using it as a plugin to logic pro. When I choose a pattern, there are some notes on the keyboard that colored in red and they don't make a sound. There are chords or notes that I just can't play, no matter what I do. For example, I want to play

Dm / Bb / A / Ab

and it just wouldn't accept the Ab, can't be played. I can select the auto chords, but then I get a fixed chords progression. But I want my own progression. What is going on?

By the way, when I open Kontakt 7 and open the guitar from there I have a full control over the keyboard and can play which note I feel like...

Thanks,

Shay
