Parts Replacement Help

Hello, hoping to get some help in replacing a part on my dishwasher. The energy selection/cycle switch is broken on my current model. I had ordered the correct part form here and went to replace the older one.

After getting things apart and to the switch I noticed that there are three metal prongs with leads coming off the back of the old switch, but only two metal prongs, and a couple plastic prongs on the back of the replacement part ( WD21X732). As I understand it, this is the correct replacement part from GE. I am unsure as to how to hook up the replacement part at this point.

Edit to add a question. Could this switch being bad also result in the heated drying not working?
Any help would be appreciated,

Thank you

Nevermind, apparently the parts diagram or the parts list in incorrect as it is not the right part, I am just going to return everything.
