Well I certainly can't blame you for that. However, it's far from clear whether the change to the catechism can even be reconciled with prior teachings at all. I only linked to one article among many, but there is considerable confusion about this change throughout the church and Pope Francis has not really offered any clarification.

If one views the argument that the prior teachings were infallibly proclaimed as incorrect, than there is no need to reconcile them; the prior teachings were simply in error.
Unsurprisingly, Francis has not only identified the previous approach as in error, he has both explained where the error is and provided an (unnecessary) explanation of what led people to make the error.

No one is confused or has any need of clarification. “It is per se contrary to the Gospel” isn’t the kind of statement that leaves a whole lot of room for different readings.
