Why isn't my Sprite Mastery Pod Back Bling unlocking the sprite styles after mastering them in Fortnite?

When players edit the Sprite Mastery Pod Back Bling in the Fortnite Locker, they may find that the Sprites or their variants mastered appear as locked or missing in the Edit Style page.

We have been also seeing reports about the most recently released batch of Sprites. Please note that the Sprite/variant unlockable styles for the Sprite Pod Back Bling get unlocked one release after that Sprite/variant is released.
