Hi,
I've been running into this problem A LOT and it's really starting to bug me.
Sometimes when I try to change font colours or formatting of a text, the characters in that text get random spaces. I've tried kerning the text and it didn't work.
I've inserted an image of what the text looks like in the text box once I grouped two text boxes together.

As you can see, the text inside the textbox is funny looking with random spaces between the characters. Towards the left of the textbox, I've written "facilitates survival" in the EXACT same font settings. You can really see the effect with the word "cognitive".
As I've already said, I've tried kerning and I saw no change.
The preview shows the correct formatting but the actual font still looks weird!

Please help me out!
Using Word 2016 (most recent update) and macOS High Sierra 10.13.1
Thanks!
