How to set two categorical vew mapping

v-viig

Here is my capabilities file. As I understood from tutorial on github, second dataviewmapping will result in two categorical data with different categories and values. When I use this code, I have two categorical data, but categories from first one also displayed in second one, whereas there is no "check_cat". At the same time, data for second categorical view displayed correctly.
