WAS THERE A TYPOGRAPHICAL ERROR IN THE CATECHISM?

In the Catechism of the Catholic Church,the sub title‘Outside the Church there is no salvation’ has been placed over N.846.It should really be above number 845.

The ex cathedra dogma says everyone needs to explicitly enter the Church for salvation. It is in agreement with n.845

N.845 To reunite all his children, scattered and led astray by sin, the Father willed to call the whole of humanity together into his Son's Church. The Church is the place where humanity must rediscover its unity and salvation. The Church is "the world reconciled." She is that bark which "in the full sail of the Lord's cross, by the breath of the Holy Spirit, navigates safely in this world." According to another image dear to the Church Fathers, she is prefigured by Noah's ark, which alone saves from the flood.-Catechism of the Catholic Church n.845

Here is the ex cathedra dogma:

1. “There is but one universal Church of the faithful, outside which no one at all is saved.” (Pope Innocent III, Fourth Lateran Council, 1215). Ex cathedra.

2.“We declare, say, define, and pronounce that it is absolutely necessary for the salvation of every human creature to be subject to the Roman Pontiff.” (Pope Boniface VIII, the Bull Unam Sanctam, 1302.).Ex cathedra.

3.“The most Holy Roman Church firmly believes, professes and preaches that none of those existing outside the Catholic Church, not only pagans, but also Jews and heretics and schismatics, can have a share in life eternal; but that they will go into the eternal fire which was prepared for the devil and his angels, unless before death they are joined with Her; and that so important is the unity of this ecclesiastical body that only those remaining within this unity can profit by the sacraments of the Church unto salvation, and they alone can receive an eternal recompense for their fasts, their almsgivings, their other works of Christian piety and the duties of a Christian soldier. No one, let his almsgiving be as great as it may, no one, even if he pour out his blood for the Name of Christ, can be saved, unless he remain within the bosom and the unity of the Catholic Church.” (Pope Eugene IV, the Bull Cantate Domino, 1441.) Ex cathedra

It says everyone needs to be a visible member of the Catholic Church to go to Heaven and avoid Hell.

So CCC 847,848 must be interpreted as referring to implicit salvation, in ’certain circumstances’ and unknown to us, otherwise it would contradict the infallible teaching.

847 This affirmation is not aimed at those who, through no fault of their own, do not know Christ and his Church:

Those who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience - those too may achieve eternal salvation.-Catechism of the Catholic Church

848 "Although in ways known to himself God can lead those who, through no fault of their own, are ignorant of the Gospel, to that faith without which it is impossible to please him, the Church still has the obligation and also the sacred right to evangelize all men."-Catechism of the Catholic Church

CCC 847, 848 do not refer to explicit salvation and so do not contradict the dogma. There is no de facto baptism of desire that we can know of.

So if asked if everyone needs to enter the Catholic Church for salvation the answer is YES.
Everyone explicitly needs to enter the Catholic Church for salvation and those who have the baptism of desire or are invincible ignorance would be known only to God.
