Time Intelligence functions not working

Hi all,

I initially had a calculated date table and all other tables in import mode in my power bi data model.

I only converted my dimension tables to dual mode and instead of generating a calculated date table, I imported the date table from SQl server in import mode and now my time intelligence functions are not working. If I get back to the calculated date table it starts working. I even converted all my dual mode tables into import mode and then imported date table from SQl server, even then time intelligence is not working. Can someone help me with this?
