Hi,
Thank you for your interest in Syncfusion products.
By default the enum column type will have the index in the filter bar as it is represented as a value. In order to have the display text in the filter drop down you need to work around with the following events such as QueryFilterBarChoices, QueryRecordMeetsFilterCriteria and TableControlCurrentCellCloseDropDown.
Please refer the sample attached in the below location:
