I made my own version of the Purple Dragon Knight subclass and I wanted to share it with the community.... but for some reason it says its too similar to the Circle of Spores... which it obviously doesn't resemble at all.. and that it doesn't have enough class features for the required levels... which it does. So I'm really confused on what's going on.

It's called Purple Dragon Knight (Banneret) Redone

Five things:

1. The “Circle of Spores” thing is usually if you don’t have enough description.
2. The system only picks up changes when the main Save Changes button is hit for the whole subclass. So after you add description, you must re-save.
3. There is a glitch currently requiring a 5th-level fighter feature that it should not actually be allowed to have. Just keep playtesting and editing and when they fix the bug you will be able to publish normally.
4. If you’re having these questions, you probably only recently finished writing it. If that’s the case, I highly recommend very thorough playtesting and editing prior to publication. Published is permanent, so if you have to make any edits after you publish, you will need to create a new version and republish it and there are very many excellent reasons to not do that if at all avoidable.
5. If your Purple Dragon Knight is based too closely to an existing subclass like the official Purple Dragon Knight, don’t publish it anyway, that would be plagiarism.

I hope that helped.

Well I put descriptions everywhere and saved after each thing I did so that can't be it. So I'll assume it's the level 5 bug.

And no, that wouldn't be plagiarism. Plagiarism would be claiming that I invented the subclass completely and copied it word for word from the Sword Coast Adventures Guide. 

This is a revised version of the subclass to address some issues I thought the original had.

If it’s too close to the original it’s still illegal and the moderators will reject it. I don’t care what you call it. And no, even copying it in part is still plagiarism. If it is not altered sufficiently to count as your own work, it will get rejected. I’m just giving you a piece of friendly advice.
