Ozone content icons

I’ve been working with the Ozone theme for a few months now on both my desktop and Pi3 and I can’t for the life of me figure out how to change some of the icons.

I know Ozone hitches onto the XMB assets folder in addition to having it’s own folder for main menu icons. However, no matter what I do, I can’t change the icon for “Favorites” content. The “favorites-content” image only changes under “Load Content > Playlists > Favorites” and not in actual Favorites menu. Otherwise, there’s a generic icon next to my ROMs.

This is also an issue with content under the Images menu.

So my question is, is this supported by the theme? If so, what’s the file path Retroarch is looking for in Ozone?
