SpongeForge Blocking Attributes Mod [Requesting Help]

I have a server and am trying to make the dragons and bosses harder by applying armor attributes to them and armor toughness attributes to them. I have it working but whenever Sponge is installed it does not work. I believe it may be blocking it. Is there a way to make Sponge stop blocking it? Thank you for reading!
