Additional context
I should mention that Sodium is being used if that's somehow causing the icons to not render for whatever reason. Also i'm not using a texture pack of any sort, or a shader, or anything else I can think of that would cause these icons to not work. In fact here is a list of my mods in the offchance there's a conflict I don't know of. https://i.imgur.com/LVps1gW.png?1

Known issue of sodium that does not support the needed render

Also affecting optifine. Think a fallback will be implanted to next release to show base texture of the item and not a invisible item.

Yes what @KnatteAnka said
