Set to HD but only recording SD

Similar issues in the UK so I don’t think this is limited to comcast channel number changes. Recordings set to Prefer HD record SD even though an HD airing is available. Recordings set to HD Only do not record. Recordings set to specific HD channel and Prefer HD record HD fine. In the guide, listings appear fine, but if I filter the guide to HD channels, the channels show but there’s no listing detail

this all seems very familiar… has a fix from about 2 years ago been regressed some how?
