Updating the firmware resolved this.

Firmware is 2.050... How do you update SunTouch firmware 🤣

The answer to this was surprisingly easy https://www.troublefreepool.com/threads/how-to-perform-firmware-upgrade-on-pentair-controllers.69589/post-2318162. Only hard part was waiting 5 weeks for the USBDM programmer to arrive from China.
