Hi,
Can you run the data verifier located in DBMC(Database Management Console)? When installing the CB server components it includes the DBMC and create a shortcut in your desktop "Connected DBMC 18.2", if incase you could not find it in your desktop, you can goto the CB installed folder e.g. C:\Program Files (x86)\Connected Business CE 18.2 Server and run the executable file "Interprise.Presentation.Utility.DBMS.exe". See the screenshot below:

Thank you and Let us know if it resolve the issue or not.
