Can’t update my Movies tab

First off, I’m running Kodi Krypton v17.1 on my Windows 7 64 bit PC as my host. I’m trying to add all my movies into my “Movies” section on Kodi. When I enter the movies tab on my PC it says “Your library is currently empty. In order for populate it with your personal media, enter “Files” section and add a media source and configure it. ETC. ETC.ETC.”

I have entered all my media sources in the Settings>Media Settings>Library>Videos sections with my multiple hard movies folders. All my various hard drives have media folders with each folder in that directory containing a separate folder for each movie. I’ve tried numerous settings in to update my library and never do my movies show up in the “Movies” main tab. It always gives me that same “Your library is empty…” message in the Movies tab.

How can I add the movies to this tab? Thank you !
