Possible Audio Bug in Unreal Engine 4.23?

I had 4.22 version and audio clips stereo and mono channels. When I jumped to 4.23 version, all my audio clips started to play glitchy (I don’t know why). Then I had to spend around a week to figure out what’s going on. After using an external software (Adobe), I just discovered that changing the speaker channel of all my audios to 5.1, the problem’s gone.
