Can't hide points in stacked chart

HI guys!
Er... that is pretty much it lol


Or, more precisely, on a stacked chart, I can't control the series points separetely. So, I need to either activate for both, or none of the series. To summarize, you can only control points exhibition for the first serie, and that changes the other one exhibition as well. I'd like to hide points for the second serie and keep them for the first - from the example, you can pretty much tell why.
Purely cosmetic, tho.

Oh, and, by the way, I had only one serie. Than I added the other column, and metabase stacked them all by itself. That was freaking amazing, nice feature.
