Kettle Job with SQL entry doesn't RUN

Hello,

I am using the Kettle GAR 5.2.0.0 Release and I am trying to run a simple kjb Job which inserts an new entry into a Sybase Table using the Native JDBC Connection. The Job consists of a START, SQL and DUMMY entry, wherein the SQL script looks like:
INSERT INTO test_link (quest_id, quest_no) VALUES ('A', 'ALPHA');

The Job doesn't execute the aforementioned SQL command (or any other SQL), although finishing correctly, and the Detailed Logging doesn't provide any further information. Please note that a similar ktr Transformation which includes an "Execute SQL script" entry runs smoothly without any issue.

Any advice would be welcome,
