Megascans claimed on Quixel Bridge and FAB, but subsequently became paid items on FAB?

Hello, I have a question regarding certain Megascans—such as ID we1jdig from Quixel Bridge (https://quixel.com/assets/we1jdig), which has now been renamed “Coast Rauk Formation Rock S 09” on FAB ( Coast Rauk Formation Rock S 09 | Fab ). This asset is part of a long list of items claimed on Quixel Bridge and FAB during Epic’s offer, meaning they are in our “acquired” collection. However, some assets arrived on FAB later; as noted in point 5 of this post (quote): “Some Megascans content is currently being migrated to Fab. Consequently, you will have a license for this content as soon as it is published on Fab. These assets will be available on Fab later this year” ( Megascans update, March 2025 ). Yet, these Megascans that arrived later—like the one I mentioned—were never added to our library and have instead become paid items? This is despite the fact that they were indeed acquired on Quixel Bridge, as shown in the images. So, my question is: why were some of the Megascans that were claimed—and subsequently appeared on FAB—never added to our library as originally intended?
