My GOLD RARE celebration changed to a NON RARE after a couple of hours

I packed the "Shudder" celebration (or shrug) I used it in game, pretty toxic celebration tbf. Closed the game, opened it a few hours later. Now it is "Rock on". Animation in game is also "Rock on". I believe the GOLD RARE celebration I packed was called "Shudder" even though they were doing just a shrug. Just wondering how can a Gold rare card celebration change to a non-rare over the span of a few hours... Food for thought.
