Just created a Spell casting Rogue subclass with Druid Spells but when on the character sheet it keeps saying "You do not have spellcasting or pact magic spells to manage. The spells that appear for your character were gained through other class features,racial traits, feats, or items." 

I've created other before with no issues, so not sure what is wrong with this one

Please see the Homebrew Subclasses & Species FAQ, question #7: (https://www.dndbeyond.com/forums/dungeons-dragons-discussion/homebrew-house-rules/131411-a-homebrewers-how-to-faq#HomebrewSubclasses&SpeciesFAQ).

So do I need a Class feature called Spellcasting? cause that's the only thing i see that is different

Does the guide I wrote say you need one?

it is the first step, but does the name of the Feature really matter? The Subclass has a feature that grants spellcasting but it isn't CALLED Spellcasting

Does the guide I wrote specify that the name of the feature must be “Spellcasting?”
