[GUIDE] How to create your own hero?

Thank you very much for the guide; it was very helpful. However, I'm having trouble with one part. I selected the "Knight" model in **"Model"**, and then the animations for that knight in **"AnimSet"**. It seems like I did everything correctly, but when I get to **"HeroCharacterArenaMelee"**, only the **"Character"** window appears, and the **"AnimSet"** that was shown in the guide is unfortunately not there, which prevents me from selecting the hero's animations. I've tried everything, but I haven't been able to resolve this issue. Do you have any idea why this might be happening? I'm honestly at a loss.
