Current Measure - 

concatenated values = VAR __SelectedValue =
SELECTCOLUMNS (
SUMMARIZE ( Parameter, Parameter[Parameter], Parameter[Parameter Fields] ),
Parameter[Parameter]
)
RETURN CONCATENATEX ( __SelectedValue, Parameter[Parameter], ", " )

Field parameters doesn't work like that. 

What I would recommend you do is in Power Query, merge and pivot your data so it looks like this

Cat 1, A

Cat 1, B

Cat 1, C

Cat 2, X

Cat 2, Y

Cat 2, Z

That way you can create a relationship to your parameter table or simplye use a slicer from the table you created.
