Adobe Sign shows my former educational institution as the final signatory, instead of me

My Adobe account was originally with my educational institution, but it has been my personal account for several years by now. However, when I use Adobe Sign, it still shows my educational institution as the signatory in the finalized document instead of me. Of course, this is creating a lot of confusion when I ask to sign a document. None of the information in my account setting refers now to my old educational institution other then, maybe, the original order number that ends with the letter EDU (just to make this clear, I have been paying the full subscription fees as individual for years now). What should I do to make myself the final signatory?
