SSRS 2008r2 ESRI Maps -> Wo to Hide Spacial Data

Hi

I've got a ESRI Map with a lot of Towns (See Picture Below)

I've got some analytical data for some of these bullets / towns. 

The mapping happens successful and I get some colored bullets, but unfortunately the remaining "null" value bullets stay in the picture, too. 

So finally I would like to hide all the remaining "no matching" bullets from the spacial data input, and show only the matched, colored bullets that are filled with the analytical values.  

Now I can't find how to achieve this....  When I set the filter, this is only for the analytical data, and not for the spacial data... should I maybe try to find another ESRI? 

Thanks for your help!
