How can I know the parent class of an animation?

Hi!

I’m using Unreal 5.3.2.

I’ve got this warning message: Warning: Class /Game/Characters/MannequinsXR/Meshes/ABP_MannequinsXR.PLACEHOLDER-CLASS__B_MannequinsXR_C_0 has parent , but this parent is not found. The Class will not be shown in ClassViewer. It comes from an animation that I have copied from the VR Template project to another.

How can I know which is its parent class?

Because it says that is AnimInstance, but I think I have this class in my project.

Thanks!
