State Definition overriding style properties.

Hi,

I have a grid which has a state formatting which changes the color (of value) of row to red after some condition is hit, and keeps it default otherwise.
I want to change the background color of row when i select a particular row, so, i applied background color on selection in style properties.
But on selection of row, the background color doesnt change only the text becomes smaller, seems like the state definition is overriding with the style properties 
I want that background color on selection, is there any workaround it ?
Above grid is the issue,

bottom is the behaviour i want
