Blend Space Animations Won't Show Up - Aim Offset

Hi everyone!

I just created a third-person project with the animations starter pack and I’m trying to create the aim offset for the character. All the animations work fine as seem here:

I hope you can see all the configurations there. So, what am I doing wrong? Is that a bug or am I missing anything?

Any help will be much appreciated.
