That is actually your second lock being detected!
When you set up a new Tapplock one, it comes with a default name "TL104A".
We recommend changing the default name of your Tapplock! You can change the lock's name through the app once it is set up by clicking onto the lock's profile and following the below steps:
- Select "Lock Setting"
- Select "Tapplock Name"
- Rename your Tapplock one
