Change data type of saved questions

Hello guys, my name is Dener and I'm new to Metabase.
Currently I'm making a question using SQL, and this query returns a table with some columns, see the image below:

The problem is that the columns "Data da entrada" (start date) and "Data da finalização" (end date) should have a date type of date, not text. I'm struggling to find out how to chenge the data type. I've seen the data model in adm panel, but I couldn't find the saved questions there, only my tables from the database.

Can you guys help me please?

Thanks in advance.

Hi @dener
Please post "Diagnostic Info" from Admin > Troubleshooting, and which database type you're querying.
If you create the question in SQL, then you have to cast the data you return in the SQL.
