mandolin chords malefunction?

[BB]

With the code I always get a 6 string chord table! And the notes are 
a-c-e-g from low to high, that is wrong for mandolin with "o;o;o;o;" as 
well! The normal mandolin tuning is g-d-a-e low to high!

(I know that for am7 I need another pattern, I have set "o;o;o;o;" just 
ti fix the problem.)


Any help appreciated!
