Training only the eyes and mouth parts of the key points, there is a strange problem

Hi，I only use the eyes and mouth parts of the key point to train PIPNET, but there is a strange problem.
I used the same model to predict key points in two videos, one of which predicted eye and mouth key points normally, while the other predicted key points at the edge of the face

This is the prediction of the same model, which is very strange

I also feel strange. For the first image, it seems you index the wrong landmarks. Please make sure you picked the correct landmarks.
