UE5.0.3 Audio Import issue

Hi Guys, I’m hoping someone can help.

I’m trying to import a WAVE file I’ve created in Adobe Audition into my UE5.0.3 project, however every time I attempt it, it fails and the Output Log gives me the same error.

Error: Unable to read wave file ‘MainMenu_Theme’ - “Unsupported wave file format. Only PCM, ADPCM, and DVI ADPCM can be imported.”
Error: Unrecognized sound format ‘wav’ in MainMenu_Theme

Ironically if I import that very same file into a UE4.26 project, the import succeeds.
