Custom audio not looping with the Radio Device

Hello everyone, I am having an issue regarding custom audio files used with the Radio Device in Unreal for Fortnite. The cue file works fine, can also be seen in-game when running live with Unreal, however the audio file does not seem to be looping by default. It goes silent once the audio has finished playing. It will start playing again when exiting a test play through.

I would appreciate any help with this. Thanks!
