As the article I linked states, for the Catholic Church it is not a matter of dogma how the Decalogue should be divided. So, I think any of the ways the Decalogue is divided, as presented, is acceptable and I don't believe there is a canon the Church has issued on how they must be divided, but I am open to correction by those better informed if I'm mistaken.
I don't have the resources handy, but the Council of Trent stated that we are required to keep the commandments of God but I don't think the Council specified a requirement on how they are divided, but again, I am open to correction on this.
I forgot to add in my last post that the traditional way of dividing them in the Catholic Church is according to Augustine, but again, it is not a dogma of the Church.
