Okay I get it, don't remember if GT ever send me that chart by mail but like that I can understand that it gets confiusing. Maybe something for GT to update that chart.

Basic Major and minor chords are made up of 3 notes out of a scale, they are called the root, the third and the 5th. To form a chord on the guitar like that you can either use them in this order or in first inversion ( being the third, then the fifth and then the root ) or in second inversion ( being the fifth, then the root and then the third ),

Chris his first example is the second inversion of the B chord, the second example just puts the B note in the bass and the last puts an other F# on the top.

In a chord voicing you can double every note in that chord so that explains that chords are not always fixed shapes but this will all become more clear if you are more advancing and learning more theory.

Hope this helpes you on your way
