Primary key must be unique

RouterOS The User Manager
1

hi guys,
I noticed my userman frequently sends this error message to LOG

Failed to add Log: PRIMARY KEY must be unique

And I think it also part of the reasons my Userman does not enforce single user signon across multiple hotspot server
ROS 4.2, Level 4
Thanks in advance.
