Only 15 Addons Shown?

I'm setting up a Kodi box for my stepdaughter, added about 25 video addons from the Kodi repo, and notice that only 15 (I think) are shown in the videos section of the addons menu. The rest are installed, and work correctly, I just have to go to "My Addons / Video Addons" to find them. Only the 15 latest-used show up on the addons menu.

Is this normal? Is there a setting for it?

Just trying make it easy for a noob to explore the addons...
