I can't seem to figure out what's happening here but on a Results slide if I make the ResultsPassPercent variable a really large size (e.g. 140 pt) it doesn't preview or publish at that size but is reduced down to a smaller size.
The above is the base layer of a Results slide with 140 pt. Below is the Preview output where you can see it's much smaller, more like 80 pt.
Any idea why this is happening?
