Catholics say they're matters of perspective; non-Catholic Eastern apologists say they're irreducible anomalies.
Byzantine Catholics' calling is not to throw out Byzantine theological methods/styles for Latin ones while only keeping Byzantine externals, nor to attack Catholic teachings like the Orthodox, but to express those teachings all in Orthodox terms. Frankly, most Byzantine Catholics, Slavic ones (the Ukrainian Catholic Church is the biggest Eastern Catholic church), aren't interested in doing that, rather going for Latin thought. Some "converts" (often born Latin Catholics and some actual converts from Protestantism) go too far in the other direction; falling in love with the rite, they mistake it for the whole church, get fed up with Byzantine Catholicism's imperfect ways (it is not the ideal the Catholic Church wants for the rite), and either leave for Orthodoxy (and often retreating to narrower versions of it when it doesn't live up to their expectations) or stay and try to change the church's teachings, which is impossible.
The Catholic Council of Ferrara-Florence clarified that the filioque means the Father proceeds through the Son.
