That's really strange. I actually have no idea as to why it happens.
Cache is supposed to comeback though, that is normal. Just deleting it once helps to regenerate some images and re-cache the new files.
I suggest you wait until the next update once it comes out, it should happen after the next stream of meme house, maybe the new repackaged version will work better for you.
Sorry for the inconvenience. I just legit have no idea as to why wont it work
