With the latest version of the SmartApp, it just means that your device handler user name is not matching what the app is telling it. It updates the names so that SmartLocks will show the same name as the SmartApp. It’s just a cosmetic thing and has nothing to do with your lock codes if they are working fine.
One quick way to fix this would be to run the Clear Codes procedure on our website which gives your device handler a clean slate and fixes and any data corruptions. It’s always recommended to run the Clear
Code procedure after you install a new lock or you change the device handler.
EDIT: This may be caused if the slot name has any spaces in it. We’ve patched it up and you can download the update
