Hello Jats,

Due to the datatype being a numeric you should set the "CurrentFilterFunction" to "EqualTo" instead of "Contains", or remove "CurrentFilterFunction".  The column will assume the filter operation depending on the type.

For information pertaining to Filtering Options, please check out our helpful documentation.  

I hope this helps!
