Unique Player Celebrations changed to 'rock on'

I had a Gold preview pack with two celebrations Gold common 'agile flip' and Gold rare 'one eye'. I checked the prices and saw the only celebrations listed were 'Rock On' so I decided to buy the pack and list the two celebrations. Neither sold in the first 60 minutes but weirdly at the end of the 60 minutes they moved to unassigned and changed to 'rock on'. 

Haven't seen this mentioned elsewhere so thought I'd flag it. Hope it helps!

I'm on PS5.
