Oh really?
The Gloss of Extravagantes of Pope John XXII says this: But to believe that our Lord God the Pope the establisher of said decretal, and of this, could not decree, as he did decree, should be accounted heretical. [The Gloss of Extravagantes of Pope John XXII, Cum. Inter, title 14, chapter 4, "Ad Callem Sexti Decretalium", Column 140 (Paris, 1685). In an Antwerp edition of the Extravagantes, the words, Dominum Deum Nostrum Papam ("Our Lord God the Pope") can be found in column 153[

we readily understand the devotion of Saint Francis of Assisi for "the Lord Pope",the daughterly outspokenness of Saint Catherine of Siena towards the one whom she called "sweet Christ on earth", the apostolic obedience and the sentire cum Ecclesia of Saint Ignatius Loyola,and the joyful profession of faith made by Saint Teresa of Avila: "I am a daughter of the Church" [Pope John Paul II, Vita Consecrata (March 25, 1996): vatican.va.]

Apparently, it is a copy of a copy of a copy, etc. The original was actually dated in the 1300's, so this copy is 300 years later.
They have found the original from the 1300's in the Vatican Library, and it says "Dominum Nostrum Papam". The word for God, Deum, is not used.
Additionally, the fact that they're arguing against a claim that they believe the Pope is God says they don't believe such a thing.
I've not been able to look at the others yet, but at first glance I'd say it has to do with their statement that the Pope is Christ's Vicar on Earth..
