Empty Energy Usage / Solar Production Chart for GivTCP

I’ve setup and configurated HA with GivTCP a few days ago and all was well and I was getting information from my solar and batteries and it produced a good couple of days worth data and the daily charts were visible. Then it stop displaying information, see below. The logs show no issues in both GivTCP and MQQT, I can’t see what is wrong.

I’ve looked at some of the devices and I can see data. However, in the Source section on the Energy page, they show this message;

This entity is no longer being provided by the mqtt integration. If the entity is no longer in use, delete it in settings.

I re-installed both GivTCP and MQTT, but I still get the same.

Anyone have any pointers?
