The problem with the filter feature that the selected operator css is not activated properly when showApplyBtn is true

[seolllll]

columns: [
{ header: 'Name', name: 'name', sortable: true, filter: { operator:'AND', showApplyBtn: true, showClearBtn: true, type: 'text'} }
]

If you select operator under the above conditions, css will not be activated properly
Let me know if it's a bug or I can't use "showApplyBtn" and "operator" together
