Awesome game but...

I have had Carnivores for around four days and overall it is an awesome game. After I had killed around twenty mamoths I deleted all of the ancient creatires from my trophies so I could make room for better carnivores now no matter what I kill it doesnt record any. I have killed many yeti and would like to show my friend please fix this, but still 4/5 stars
