Hello, I made and put a homebrew subclass in one of my character's sheets. I put the description both in the required part, the snippet and the multiclass description but it refuses to show up in the actual character sheet, and Idk what to do. 

You can leave the Multiclass section blank unless the character works differently when multiclassed than otherwise. The only parts that show up on the character sheet are the snippets. Please see the Subclasses & Rees FAQ #s 6 and 6-B for answers to your questions: (https://www.dndbeyond.com/forums/dungeons-dragons-discussion/homebrew-house-rules/131411-a-homebrewers-how-to-faq).
