Emoji Switcher not working on Marshmallow (Nexus 6)

I flashed the stock 6.0 images from google, then I flashed the modified boot image which allows root from Chainfire (http://forum.xda-developers.com/apps...ellow-t3219344). I also have supersu beta v2.52. This is a screenshot of my phone's properties:



I have installed emoji switcher 2.0.1 and when I try to switch my emoji's from stock I get this:



I have flashed busyboxM from http://forum.xda-developers.com/nexu...eview-t3123285.

Is there something else I need to do or does this not work on Marshmallow yet?

Thanks,
Tim
