Covers downloaded through WiiFlow do not show for Wii games

Describe the bug A clear and concise description of what the bug is.

As simple as it sounds: I have over 1300 Wii titles and confirmed their covers' existence after downloading via the built-in function. They do not show. Only a handful show and there's no pattern that I can see. I've restarted several times, reloaded themes, reloaded cache.., it's like they're just being ignored at random, perhaps due to a memory shortage?

I should note I also have over 500 Gamecube titles and a majority of their covers (downloaded the same way) show up in the separate GC category.
