Error- source was visible but ignored

I am trying to blend two animations—one for the upper body and the other for the lower body. I plan to use these blended animations in the sequencer for rendering a character animation. However, after assigning the slots and adjusting them in the blueprints, I am encountering an error for the default slot node stating, “Source was visible but ignored.”


This show the blueprint that I used


These are the settings for layered blend per bone node


This is my animation montage viewport and slot allotment to the other animations
