After some searching I found this post: http://support.advancedcustomfields.com/forums/topic/repeater-on-options-page-returns-count/
Which doesn’t directly apply to me as the code isn’t in functions.php, but it does imply that the repeater field “is not yet loaded and can’t run it’s custom load_value logic”.
I made the category page template in question (category-music.php) after installing ACF and creating the fields, do I have to register the new templates somehow?
