BUG: Matrix + Field Parameters + Groups → Order not respected

A Matrix does not preserve slicer click order. For a field placed on Columns, the Matrix always applies a deterministic sort order for that field. With Field Parameters, the “field” is the parameter table, and the Matrix sorts it by the parameter’s internal ordering (effectively the order column / the parameter row order you created which is what your “groups” end up enforcing).

In the Field Parameter table there’s an order column (often named something like Parameter Order). The Matrix will respect that, not click order.

• If you need a stable order, design it into the parameter table

• Use Sort by column on the display column

This won’t match “user selection order”, but it will be consistent and predictable.
