In the connection properties, the Advanced tab is selected. Then check the box next to βUse advanced connections.β Finally, check the box in your database. Done.
I thought that I might have to use "Remove DB from List", but I did not. After performing the above steps, Navicat only shows my database, which is exactly what I wanted.
I also have Navicat Premium Essentials (11.1.7); Purchased through the app store.
