I tried Valentina Studio Free (both on Mac and Linux), with an existing sqlite database but I have some problems with missing fields.
For example :
What is created and OK in other DB Tools :
In VS table1 and table2 seem OK but table12 show no field, or only one.
I created this database with SQLite Studio, I also open this database with DBeaver, DB Browser for SQLite and DBVisualizer and all tables are OK.
So what's wrong with Valentina Studio ?
