Corrections getting rejected

I was making some corrections to the classification ratings on Unicorn Wars, due to them being glaringly wrong, but it got rejected with the reason being "unable to verify". But I already gave reasons for my changes, and there isn't a whole lot to "verify".  Moreover, I find it highly unfair that someone can just add false information that easily with zero evidence to back it up, but the burden of proof falls on me if I want to correct it.

Can someone please look at them and revise it?
