Okay new version custom fonts are not working for me at all!

I can't figure out what I am doing wrong.
I choose the font in themes and click apply but nothing changes
This is on my Nexus 7.2 by the way. I'm going to try on SGP and see if works on there.
Works on the SGP but not on the Nexus 7.2

Same fonts files too.
Downgraded to 2.4.0 and custom fonts work again but of course custom italics and bold don't due to not being added yet.
UPDATE:
Okay here the weird thing. This was a fresh install on a new tablet that never had Mantano on it. I installed 2.4.6 Google Play edition. Custom fonts wont work. Tried uninstalling and reinstalling twice, restarting the tablet, deleting the Mantano folder and nothing. So I downgraded to 2.4.0 Amazon app store Edition and then uninstalled it and Upgraded to 2.4.6 Google Play Edition and now it works as it should!
So my guess is a fresh install isn't creating something that is needed to display custom fonts on the Nexus 7.2.
