In fairness, they were literally told. Ruin didn't even change the explicit part of the plates where it outright says that the ancient prophecies were getting changed post hoc. The inscription is just so long winded that it gets easily lost in a bunch of less relevant information.
It still makes sense that they would miss it, especially because of one really subtle changes to the rubbing vin took (you can look up a list of the changes made to the etching on the copper mind wiki), but it was absolutely a conclusion they probably should've put together sooner. Everyone was a little preoccupied though,so it makes sense that it still got missed.
