A non-baptized person took place in a Catholic wedding?
Wondered about that too. My only explanation is that they started the process that way.
A Catholic can validly marry a non-Christian with a dispensation. See:

Catholics may marry non-Catholics with a dispensation.
Also you know that there's a difference between a nuptial Mass and a Catholic wedding, don't you?
Can. 1059 The marriage of catholics, even if only one party is baptised, is governed not only by divine law but also by canon law, without prejudice to the competence of the civil authority in respect of the merely civil effects of the marriage.
Can. 1086 §1 A marriage is invalid when one of the two persons was baptised in the catholic Church or received into it and has not by a formal act defected from it, and the other was not baptised.
§2 This impediment is not to be dispensed unless the conditions mentioned in cann. 1125 and 1126 have been fulfilled.
Can. 1118 §1 A marriage between catholics, or between a catholic party and a baptised non-catholic, is to be celebrated in the parish church. By permission of the local Ordinary or of the parish priest, it may be celebrated in another church or oratory.
§2 The local Ordinary can allow a marriage to be celebrated in another suitable place.
§3 A marriage between a catholic party and an unbaptised party may be celebrated in a church or in another suitable place.
CHAPTER VI : MIXED MARRIAGES
Can. 1124 Without the express permission of the competent authority, marriage is prohibited between two baptised persons, one of whom was baptised in the catholic Church or received into it after baptism and has not defected from it by a formal act, the other of whom belongs to a Church or ecclesial community not in full communion with the catholic Church.
Can. 1125 The local Ordinary can grant this permission if there is a just and reasonable cause. He is not to grant it unless the following conditions are fulfilled:
1° the catholic party is to declare that he or she is prepared to remove dangers of defecting from the faith, and is to make a sincere promise to do all in his or her power in order that all the children be baptised and brought up in the catholic Church;
2° the other party is to be informed in good time of these promises to be made by the catholic party, so that it is certain that he or she is truly aware of the promise and of the obligation of the catholic party
3° both parties are to be instructed about the purposes and essential properties of marriage, which are not to be excluded by either contractant.
Can. 1126 It is for the Episcopal Conference to prescribe the manner in which these declarations and promises, which are always required, are to be made, and to determine how they are to be established in the external forum, and how the non-catholic party is to be informed of them.
