The NULL issue (in the first screenshot) is a result of the way Tersus creates database schema. Namely:
It looks like you created myTable twice. First it included an ID field (which was the initial primary key), and then you removed the myTable definition and created it again, this time without an ID primary key, but since the myTable was already defined in the database, the ID column definition remained.
The second issue is due to the fact that you named one of the fields POSITION, which is reserved in the sql dialect of hsqldb (the database server embedded in the studio).
