Encouraging to see who he does and does not acknowledge as his fellow Christians.
If that's it, it shouldn't be surprising. Mormons are not Chrisians in the historic sense. They do not have a Nicene Christology and do not recognize Jesus as the Only-Begotten Son, Who with the Father and the Holy Spirit, the three persons are are the One God; they do not believe in the Trinity. They do not believe in the closed Canon of Scripture, which means that public revelation ceased with the death of the last Apostle.
The Ctholi Church does not believe that a MOrmon baptism is a valid bBaptism, because they mean something entirely diffeent b i. In contrast, th Catholic Church recognizes almost ll other Christian ecclesial cmmunities' pracice of Baptim as valid. If a Calvinist, for instance, were to be received into the Catholic Church, he or she would not be re-baptized. Three is one Baptism, and they've got it, that's it, with very few exceptions (e.g. Jehovah's Witnesses.)
