Hello @JordanS721 ,
With the file you're trying to upload into the system, have you checked:
I looked in your account and didn't see any recent contact upload or download history either. Is this a list you haven't actually uploaded yet? Please keep in mind that the contact field selector screen only shows a preview of the first 5 rows you have information in, for the sake of making sure contact fields are properly matched to the correct column. This doesn't mean our system is only going to upload those 5 contacts.
