The short version: the chords field format changes if I use personal transpose.
The long version: When I use the chords field, I include words like 'intro' and 'verse' for different sections. If a verse has two lines of chords, then I will space-bar that second row so all the chords are aligned. Recently, I have found using the personal transpose makes the left-most chord symbol completely left-justified, with all other chords staying where they were.
Can you post a screen shot showing an example of this?
