In your dataSource the “start_date” field value is a string
not a date object or ISO date string. So, the type and formatting will be
applied only for showing the string value as a date. For data actions like
filtering, we need date object to filter properly. This is the default
behavior. So, you need to either convert the string value into date object in the
data source before assigning it to the Grid or change the column type as ‘string’
and remove the formatting to overcome the reported issue.
