The former just needs a refresh - it's loading the cached version of the old icon. The latter haven't been updated yet. If you submitted the rest of those, there was some sort of error and they need to be re-uploaded. Keep in mind that, just for now, images must be in the PNG format. Additionally, they must be exactly the right size (which is visible on the normal submission form).
