It's probably because these new episodes are about entirely new characters. Keep in mind the main target audience of the Loud House audience is children, and chances are kids probably either don't recognize the Casagrandes (since they appear so rarely in the series) and don't know what's going on or don't care for them and just want to see more of the Louds (which is sad because I personally think the Casagrandes have some potential). I'm not speaking for everyone, including kids, but that's just my theory.
