Minor - UEFN & Creative Play - Audio track added in the sequencer was hearable in UEFN but not in Creative Play

I created a sequence where a bookcase slides away and a hidden path is revealed. I added 2 soundcues that work while listening to it in UEFN but you can’t actually hear them once the sequence plays in Creative Play mode.

Repro by adding an Audio Track to your Sequencer. Play the sequence when interacting with a button in Creative Play. Result in my case: the sounds don’t play.

EDIT: Converted the .ogg back to .mp3 and then back to .ogg and imported them as new sounds and made new soundcues. This fixed the problem? After this I could hear the sounds in the sequencer in UEFN as well as in Creative Play and ALSO in Creative Edit when hitting the speaker with the sounds on it with my pickaxe. Still weird that the old sound I imported only worked in UEFN and not Creative Edit or Creative Play.
