It isn't a problem that your popes teach contradictory things? Particularly when it is Catholic doctrine that your popes are preserved from teaching error?
Whether or not Mary died is not doctrinal, and Catholics are free to accept either one. Popes are entitled to their opinions, and based on what I've read from the last few popes, they say she did die.

Odd that you would quote one of the strongest opponents to the doctrine of the Immaculate Conception.
“I answer that, God so prepares and endows those, whom He chooses for some particular office, that they are rendered capable of fulfilling it, according to
2 Cor. 3:6
: ‘(Who) hath made us fit ministers of the New Testament.’ Now the Blessed Virgin was chosen by God to be His Mother. Therefore there can be no doubt that God, by His grace, made her worthy of that office, according to the words spoken to her by the angel (
Lk. 1:30
,
31
): ‘Thou hast found grace with God: behold thou shalt conceive,’ etc.
But she would not have been worthy to be the Mother of God, if she had ever sinned. First, because the honor of the parents reflects on the child, according to
Prov. 17:6 ‘The glory of children are their fathers’: and consequently, on the other hand, the Mother’s shame would have reflected on her Son. Secondly, because of the singular affinity between her and Christ, who took flesh from her: and it is written (
2 Cor. 6:15 ‘What concord hath Christ with Belial?’ Thirdly, because of the singular manner in which the Son of God, who is the ‘Divine Wisdom’ (
1 Cor. 1:24) dwelt in her, not only in her soul but in her womb. And it is written
Wis. 1:4 ‘Wisdom will not enter into a malicious soul, nor dwell in a body subject to sins.’
Summa Theologiae III:27:4
Even though Aquinas did not claim that Mary was sanctified
from the moment of her conception, he did claim that she was sanctified
before her birth, and so never committed personal sin (for unborn children commit no personal sin.
Thus you should never tolerate someone to say that Aquinas endorsed the idea that Mary was sinful.
He absolutely and unequivocally did not, and you should ask any Protestant/Orthodox who says this whether he has actually read what Aquinas said on the subject or whether he is repeating erroneous claims made in anti-Catholic sources. If he is doing the latter,
he is repeating gossip. If he is doing the former, and really does know what Aquinas said,
then he is being deceptive.
