calculated columns not working with Dynamic filtering in SharePoint -SharePoint Online

I have used dyanmic filtering based on a calculated column various times.

But when i tried today i can;t see the calculated column display the column when enabling Dynamic Filtering in the List webpart

The list webpart doesn't show the column

Above is the way i created the cal column But When i configure the list webpart it doesn't list the column name.

Any adice or has anything changed. I confirm with my previous setup and it was working but new setup see not to work

Thanks in Advance
