Select filter doesn't work with smart rendering

Hello,
I am just using smartrendering without dynamic loading to populate my grid. But as long as i enable smartrendering by using mygrid.enableSmartrendering(true) one of my select filter will populate with duplicates items.


If I make smartrendering false It will populate select filter with unique value in column just fine.

can you please help me out.
Thanks!
