Audio Component Get Playback Percentage broken.

in my projects the “On Audio Playback Percent” Event from an audio component constantly returns 0.00. It only worked correctly when setting up a new project and only as long as you don´t restart the editor. After restarting I´m back with the same issue. Tried different audio tracks and everything, verified my engine etc. Already issued a bug report “Case # 00078927”.
Couldn’t find anything on this issue. Hopefully it’s just me, currently reinstalling the engine.
It has the correct audio output and the event fires, just has the incorrect output.

Edit: Tried it in: 4.19 & 4.21 with fresh projects, problem persisting.

Hopefully someone has an idea.

Best regards and thanks in advance.
