Tried making a 3.5 class as a subclass in 5.5

So i tried making a Dragon Shaman from DND 3.5 to be a ranger Subclass(thought it was the closest fit hp and skills wise). For some reason it wont let me publish it saying it resembles Circle of the Spores Druid and "This homebrew Subclass does not have the necessary class features with the correct required levels."

I did follow the 3,7,11,15 guides for ranger 5.5, and i tried looking through the Circle of the Spore druid to find any similarities. I'm not sure if this is a bug in the system mis-reporting something or if i did make it "similar" in a wording or feature like way?

Sorry, to make it easier or to help clarify:

This is the class in question. (I DO NOT HAVE IT SET TO OPEN IN NEW WINDOW)

Ah thank you very much, I've saved it many times with the main, but just tried it and it can now be shared! Then again im not sure if some one saw this post and fixed it behind the scenes either lol

OH that is really confusing lol. thank you very much. if it helps i do have it published if you wanna check it out ^_^
