Debugging query I do not see result rows (no replies)

Hello,

With mysql workbench 6.3 under ubuntu 18 when I want to debug some sql I click “Create a new sql tab for executing queries” toolbar item
and new tab editor is opened. When I click “Execute the selected portion...” toolbar item I see info on the sql executed,
but not result rows, as I expected .
1) Is it some hidden area?

2) I do not want to use all my databases on this connection, How can I hide some databases, without deleting them?

Thanks!
