How can I fix animation orientation?

Hello there.

I am trying to make a layered animator for aiming animations.

When I try to import animations for aiming though, the character ends up pointing in the wrong direction

This is despite the character being orientated correctly in C4D

Does anyone know how I can fix this?

Below is a gallery with more pictures that might (might not) be relevant

Thanks in advance for your help

Is there input that is controlling the direction the character points?

Is the character pointing correctly in other animations - but facing incorrectly with only the aiming animation?
