Email notification – missing space

When the applicant receives an email, it says “Your application for the position of[JOB] at [PLACE]”

Would it be possible to add a space between of and [JOB]? I believe this is to be set at https://plugins.trac.ww.wp.xz.cn/browser/simple-job-board/tags/2.10.8/includes/class-simple-job-board-notifications.php#L386

Or is there a way to change the email message otherwise?

Thanks
