SQL Syntax Checker points out wrong line

The SQL Syntax Checker underlines the wrong error.
SC underlines the blue part, but that line is OK, the error is found in the red part, by the last LEFT JOIN.

I'm using version 5.2.59.

SELECT pk_orr_kostnadsrader_id = COALESCE(ok.pk_orr_kostnadsrader_id, 0)

The error is returned by the database server engine, not by SQL Assistant. The database error message is not very specific. It simply indicates that there is an issue with levvillkorid and no specific line number is provided. SQL Assistant finds the first reference to that text and highlights it. That is by design.
