AnimBP weird layer blending

[Asterix-Us]

So I was playing with the animation BP but now it's in the state that i downloaded it and for some reason, in the AnimGraph, when the layer blending is done between BaseLayer, OverlayLayer and the BasePoses, the BasePoses don't figure as active (see attached photo). And I cant really understand why because it should :( (no changes at all have been made to the BasePoses layer itself)
