See this post on how to check if your lock is communicating directly with the hub, through a buffering device or through an unknown device (if you see an unknown device then it’s definitely an issue).
You can safely ignore this, if you want to use S2 pairing you need to select Generic Z-Wave device while trying to pair the device in the new ST App instead of “Scan nearby”, but it has no effect on the functionality of the device and the issue you’re seeing.
Since it’s pairing it most likely needs to be routed though a known buffering device.
