 ## Limitations
+
 - If the [**Spoor**](https://github.com/adaptlearning/adapt-contrib-spoor) extension is disabled (or not installed), **Language Picker** will not remember the learner's language choice from the previous session.
 - Switching languages during an [**Assessment**](https://github.com/adaptlearning/adapt-contrib-assessment) will reset assessment attempts.
 - Language Picker is not yet compatible with the Adapt Authoring Tool.
 
 ## Notes
+
 If the [**Spoor**](https://github.com/adaptlearning/adapt-contrib-spoor) extension is enabled and the course is being run from an <abbr title='Learning Management System'>LMS</abbr> that has support for the `cmi.student_preference.language` data model element, the spoor extension will record the learner's choice of language to that data model element. Note that this is for reporting purposes only: as support for that data model element is not mandatory in SCORM 1.2 it cannot be relied upon for saving/restoring the learner's choice of language - the `cmi.suspend_data` data model element will be used for that, even when `cmi.student_preference.language` is available.
