@David Campbell , I’d been discussing this with our Learn content team.
Learning paths are designed to help you prepare for all of the main areas covered in the exam, however the exam may have content not covered in the learning paths. The study guide listed on the exam page is the most comprehensive guide to what content will be on the exam.
If you wish, you may challenge the exam item on SLAs using the exam item challenge process
Thanks for bringing this to our attention. Much appreciate your feedback!
