Describe the issue

This might be related to the previous preset bug, but not entirely since the symptoms differ slightly.

The problem is that I can't exit the heat_8_15 preset after it's been active for some time (hours-days). If I try changing preset back immediately after enabling heat_8_15 it works, but every other day I discover that it's stuck in this mode. (I have an automation that switches preset between heat_8_15 and none-preset, as well as set temperature, since I'm on hourly energy rate)

Exiting the preset back to normal (none) isn't working neither through the climate card nor programatically through automations. In automations, I've tried both:
- device_id: xxxx domain: climate entity_id: xxxx type: set_preset_mode preset_mode: none
and
- action: climate.set_preset_mode metadata: {} data: preset_mode: none target: device_id: xxxx

I've seen the following error thrown in the logs intermittently, "Error in get_status Expected status code '200' but received '500' Response body: {"code":5001,"message":"DB system error due to db system"}"

A workaround is to toggle the unit off-on, then the preset change works again. But I feel like that increases wear on the unit. Rebooting HA doesn't have any effect.
