Unable to change Editable Grid Appearance (font, color)

Hi,

I have created a process with three pools, each pool contain editable data grid which is populating data. I am able to change EditableGrid appearance (font, size, color ) on first pool. But on other pool it is not applied in effect its showing the default style on other pools.

I am using community edition 6.4.

Any idea on this?

Thanks Manoj
