Font not refreshing. Any quick way to refresh labels?

I have a bit of a problem with fonts in Unity3d. I had my font files at this directory Assets/Data/Resources/fonts/
Then I decided to move the font files to this directory Assets/Resources/fonts.

My problem is the labels in my scenes are blank (they are using the font that I just moved). In order to display the font or refresh the font, I need to click or highlight each label.

So I was wondering if there's a quick method to refresh all the labels in my unity project or am I doing something wrong here?

Thanks in advance
