Internal edges Surface not consistent

gio_mi

Hello community, is there a way to adjust the curved surfaces (in the four internal edges) in order to have a linear shape?
I used the loft feature in order to create a curved edges container, this feature I presume created that inconsistent internal edges surfaces.
Here the link of my project: https://cad.onshape.com/documents/2648ae6a577e4cc7649d3ecd/w/429c54c8ed0950c2cd168c8e/e/51247de02d9b061fc23d5538

Thanks in advance

Loft is a little unhappy when the number of entities in each selection is not the same. There is a  way to deal with this during the loft but adding fillets after may prove a little simpler. Sample attached shows a couple of fillet options.
