COP and Heat Output - graph anomaly

On my local instance some of the heat output bars and COP dots are not showing.

The hosted version looks OK though. Emoncms - app view

The local emoncms log shows the following:
2024-01-08 21:00:45.422|WARN|feed_model.php|Feed model: Requested feed does not exist feedid=31

I think 31 was heatpump_dhw which I ended up deleting and recreating in an attempt to resolve an issue I am having with that feed not synchronising.
