A strange device info appears after I add a new device for my account

After I added a new device to my account, I just noticed that, besides the new device I added, there is an additional strange device ID I don’t know in the device list.

Is it normal for that?

I removed that device from the list, and I hope it is just a bug.

If you have 1 device and you add one, there should be two devices in the device list.
So seems normal to add a new id in a device list

yes. there should be two. But I see three.

I remove that additional third ID and everything works well.

The strange unknown device name is in the red rectangle.

After formatting disc and installing operating system and Jami with Jami account from backup .gz file, there is also a device listed under “Other linked devices.”
