Minx returning blank row

I'm trying to understand why the following DAX expression executed in DAX Studio returns a blank rows.  I don't see an explanation in the documentation about this.  I'd prefer not to have any rows returned vs a blank one.

DEFINE
    table t = {(1)}
    var _filter = filter(t,[Value]>1)
     evaluate {
        Calculate(
            Minx(_filter,[Value]))
    }

Furthermore, why this expression returns 1?  I thought Calculate applied the filter prior to the expression.

 DEFINE
    table t = {(1)}
    var _filter = filter(t,[Value]>1)
    
    evaluate {
        Calculate(
            Minx(t,[Value]),
            filter(t,[Value]>1)
        )
    }
