Same Character Controls as Sample, but Character not Moving Right

Hello.

Feeling a little frustrated. The only way I can seem to get this to work correctly is if I start a new Third Person Template, then rename the sample character. If I try to create my own–even if I use the exact same settings–it will not work. I have even had both Blueprints open simultaneously and matched the settings, same skeletal mesh, same camera… everything exactly the same, yet the results differ…? I’m really confused.

I haven’t been able to get the character to move in the direction the camera is facing, ever since I updated versions after I think 4.10. Up until now, I’ve just been using the template thing but I’m frustrated and feeling slightly incompetent. Can someone please help me figure this out?
