How to express to select only one value

[JustinDoh1]

I have a Pbix file here.

I have been trying to use a right term to select only one value here, and I have been just using SelectedValue.. 

What I am trying to do is "select 1 value".

Based on expected outcome of value, it should not show any results (expected outcome should be 0), because it should go under "Not Eligible" category on the visaul, but, it shows up as 1.

How do I express it correctly?

Even the tooltip shows you clearly that it's not true for the filter context of the row you're looking at to filter data to a single step... I suspect you don't fully understand what SELECTEDVALUE is all about. Please consult https://dax.guide/selectedvalue 

By the way, your model is a bad one. Very bad one. And it has RI violations in it. You've got a lot of work ahead of you to make it right.
