I opened my database with valentina studio to make a short SQL-Select.
Everything works fine and result locks good, but I can see following warning (see attached file).
Then I opened my database with my app and run reindex database and diagnose database but I can't see any error in the Logfiles and after using valentina studio again I got the same warning.

How can I fix that?

I added screenshot, log file and database..... there is nothing in it which nobody should see.
