Personalization Token Not Showing

I have an email that includes multiple personalization tokens. When I preview the email, all but one are showing up.

Am I doing something wrong in the email editor or is there something wrong with the way the token was set up by my colleague?

In the below image, the ALL CAPS colored text are the token previews. There should be a purple one showing next to the purple icon.

Never mind!!! I went into the source code and was able to fix.
