When rendering XAVS-S any audio rendered is properly separated into the channels selected. ( Left / Right Channels)

I recently noticed when rendering a XAVC Long Project the audio channels render improperly giving any selected audio track a very echo-ye sound. It sounds like both channels are just playing at once. Wonder if we could get a fix for this.

You can hear the difference.

Here is a quick b roll; same audio clip was used NOTHING was changed other than export setting.

The XAVC-S clip audio is rendered correctly; XAVC-L is not.
