I'm having trouble with creating a plane wing using the loft feature between two different airfoils

I am currently modeling a B52 Bomber and have ran into a problem while creating the wings. Whenever I use the loft feature and select one airfoil, and then the other, it just doesn't work.

If anyone has a solution please let me know: https://cad.onshape.com/documents/1186b7ba783480919ff0bbd0/w/ccd66d15efeebb87b376e1b6/e/098dad38282d4e9186efc4dc?renderMode=0&uiState=6907c77761057bc22ffa99d3
