Describe the question How to remove the brown-color Categories

Screenshots

I found, from Plugins - CustomizeAdvanced - Advanced options - doNotDisplayCategoryLeftMenu, it may be relevant, but when I check/uncheck it, the brown color Categories just remain.

Is there any other options/places I missed?

do you mean the section title "Categories"?

Exactly.

May I remove the title by checking or unchecking that option doNotDisplayCategoryLeftMenu?

After installation, there has been a default category, default, and all the videos are put into this category.
