I'm having an issue when trying to create a version for packaging. This is the message I am getting:

"ContactWithTasksRecordPage: Component [force:relatedListSingleContainer] attribute [relatedListApiName]: Could not find related list [AttachedContentNotes] for entity [Account]"

I am completely clueless as to why this is happening. I've got a Single Related List for Contacts that shows the Notes for the related Account on the Lightning Page. Any ideas?
