I do not see any active trouble conditions on your account, and the status of the lock looks ok.
Since this is on a GC3 and it looks like you have partitions enabled (2GIG calls these “Smart Areas”) I do recall some bugs on the GC3 where trouble statuses would not clear due to multiple partitions.
2GIG never did resolve the bug. Since there are no active alerts reported by your panel, this alert can be ignored if the lock is functioning normally.
