Inconsistency with accessing playback bar masters

I have just been looking at Comment Macros to control masters on virtual playback bars and found things a little inconsistent with the Goto command. It's actually Goto which seems wrong.

So, to send a Go for Cue 1 on Playback Bar 1, Master 1 - the comment is GM11/1 which makes perfect sense following on from Master 10 on the main playback bar.

However, if I use the command line i'd have to type Goto 12/1. I guess the Grand Master is being included somewhere to make the main playback bar 1 thru 11, but I don't think this is right in this instance.

Please could you take a look?

Cheers
