Idea 139.1116.4 unable to resolve db items

I have a ddl and a dml files. I create a datasource based on that ddl file. When I open that datasource, press F4 on a table, Idea takes me to the "create table" command for that table in the ddl file. That means the datasource works correctly.

I add a JPA facet for the module and assign the above datasource to the this module (right click on the module in the Persistence panel). In 2 idea versions back, Idea understood all the tables, columns in the dml file. Now this version says it cannot resolve any table nor column. Is there anything changed in Idea related to this? Or did I do anything wrong?

Regards.
