Multiple Boolean Filter; Not Working As Intended

I have 7 boolean filters as buttons. When one of them is selected "true" all the other ones automatically take "false" and lock the value. When these same filters are in dropdown format, no other values can be selected when the "false" values get locked. 

This is not how it should work. Multiple filters can be "true" at a time. The filters do not depend on each other, they're not connected at all. 

As seen the in image below, another filter is selected "true". The Education filter has automatically taken the value "false" and the value "true" is not showing.

How do I fix this issue? Thanks.
