Any track that is 10 minutes or longer allows the Artist/Publisher to distribute it as an EP where the price will be $9.99.

They do that by following the steps here:
Set price of content on your Artist page
You would need to contact Charis Studio to determine if an error was made when the content was submitted. They do have a presence on Social Media platforms such as Facebook, Instagram, and Youtube where you may be able to ask that question to them. Apple will not be able to change the price unless initiated by the Artist/Publisher.
