How to cancel old suatus for deleted objects?

Hello,
I’m setting up this fantastic tool. I’m also doing some test to understand the usage.
I often see errors in the log because Hassio can’t find anymore some device that I have deleted from the configuration.

As an example, when I was testing Owntracks I tested with some ID that now I have changed to have better understanding.
Hassio has the last status in memory and continues to show it, regardless the fact that doesn’t receive anymore this data. I deleted the entry from known_devices.yaml but it continues to add it.
This is what I get in the status.

[device_tracker.albhass_phone]

source_type: gps
latitude: xx.7059038

How to delete this status?

Thanks

Al
