But when I do it, wrap word, change the value, put a space after the text, just like in the video I end up with this behavior; the text is off on the left.
I confirm. This is a bug in Mac version only. It depends of the Total digits parameter, the size of the container, and if the Word wrap button is activated. Instead of pushing blank space (or the empty digits space) before the append value on the next line, those spaces are applied in the line before. So it create a misalignment, and text are not centered anymore.
