Android : Android - Resource Configurations Not Working

I am currently trying to update my layout for multiple screen sizes. I am attempting to set the left margin of a button. I have the button set to the proper @dimens resource. When I change the value in the values/dimens.xml the button margin changes.

However, when loading the nexus 9 in the emulator or genymotion emulator they will NOT use the values-sw720dp version of the dimension.

My values folder

values/
    values-sw720dp/
        dimens.xml
attrs.xml
colors.xml
dimens.xml
etc..

I can not figure out why it will not read these values. I am testing it on 5.0 lolipop, and the min android level is 13.

I have double checked the resource is named correctly.

Anyone have any idea?
