Xamarin Forms labs nugget package intallation

Hello

I was trying to install xamarin forms labs (android project) and i am getting a lot of this errors:

Attribute "state_selectable" has already been defined
Attribute "state_range_first" has already been defined

I am using Xamarin.Forms.Labs Core 1.1.1-beta3

I know this discussions are for xamarin forms, but has anyone had the same problem?

Thanks!
