Demo limitation?

Hello,
I’m testing demo version with PostgreSQL as DB.
I cannot setup more than one table as detail table in master detail view.I can set it up in configuration as demo project does.
But when I generate the site I can only view one table in the detail menu (usually the last one configured in the list)As well my lookup tables are not working (I set it up but the value is blank in site)Is a demo version limitation?
Is a PostgreSQL issue?Thanks

There is no such limitations. If you have enabled User Level Security, make sure you have set up the permissions properly.

I’m using admin account with all grants. Any other suggestion?

Make sure the database user you enter in the project has permissions to access all the tables.
