Why does Datagrip suggest in the hint a column that doesn't exist?

I type: ‘Select * from customer where ’ and I see a suggestion ‘where customer_id = 0;’. I hit tab to accept it and find out it's showing customer_id in red. It's supposed to be customerid. 
Why is Datagrip suggesting a column name that doesn't exist? I have to hover over the table name so I can see all the column names.

Using Datagrip 2026.2.6 with Postgress datababase.
