Wrong result by datafilter when using with domain data source

[Manoj]

I have added 2 filters as shown in attached image. When you delete both very fast. it removes only first deleted filter from result records. It doesn't corrects record as per secound deleted filter(Deleted filter before reloading grid as a risult of first filter delete). 
How to fix this issue. Please suggest.

XAML code

<!—UnBound mode Filter-->
