Limitations field parameters in visualisations

Hi All

I´m working on a multi language report were I use field parameters to let users pick language in report.

In pic Thai is selected and it works in visuals on right not on left.
when testing I´ve noticed that visual on left only select paramfield with lowest sort number disregarding slicer choise. 
If I for instance change english sort 0 --> 4 I get swedish instead that has sort = 1

I´m currious if anyone know why this is and also if anyone has a workaround.
