Bug in rewards in divisions rivals getting all untradable players

I am reporting a widespread visual and technical bug regarding promotion rewards across several divisions, including Legendary III, II, I, ..and FC Champion.

As shown in my evidence, the reward UI for these divisions lists the high-end player rewards (such as the 107-115 Festive Fixtures Player) as tradable items. You can clearly see that these specific packs do not have the "untradable" icon, while lower-tier packs right next to them do have the icon. This confirms that the game is advertising these as tradable rewards.

I have successfully reached these divisions and claimed approximately 5 to 6 players, but every single one was delivered to my club as untradable. This is not an isolated incident but a consistent error through the entire promotion ladder. I have verified that these cards are not locked in any active lineups, benches, or used as team badges.

Impact:

Because I earned these rewards specifically to sell them, this bug is causing a massive loss of roughly 1 Billion coins in potential market value.

Please investigate why these promotion rewards are defaulting to untradable and provide a fix
