You have 2 categories in this database. You can only have 1 category to store records in the database directly.

Hmm, i have 2 categories, works fine. What is that warning then?

It is not a warning. It is just an explanation which tells you that in your current set-up you can’t switch to the mode where no categories are used.

Ah, okay, so i can have as many categories  i want?

Of course.
