At the moment, the application displays just data that is the last one by the time of the message and they are not processed additionally.
Thank you for letting us know about this issue, we will work on a solution to check the validity of the last location. This will take some time to fix. We are sorry for the inconvenience.
For your part, you can additionally check the tracker settings. Perhaps there is an additional setting that leads to the sending of such a message?
If you have additional information on this model of the tracker, for example, a protocol, then you can send it to us and perhaps we can add this model to the list.
