Ideally yes, Scotch Bonnets will have a bonnet shape. It is not always the case though.Â

Believe it or not, the pod on the right is supposed to be an MoA Scotch Bonnet. Even though it looks more like a Naga, the heat and flavor were exactly the same as the more ideal, bonnet shaped pods. It was just an off pheno pod apparently. As far as what you have, is it just some of the pods on the plant that are "off", or all of them? If some pods look like normal bonnets and other pods on the same plant do not, then the oddballs are just off pheno pods. If none of the pods look like bonnets, then you are likely growing something else entirely. Also, pictures would help.
