How to handle job title mismatch in documents while applying for Work permit

[imdsumit]

What job title should I mention in Canada Work permit application, if my documents contain software engineer in some places and software developer at other for the same company?

My offer letter, reference letter mention job title as Software Developer, while salary slips and experience letter shows as Software Engineer.
