Audio track only on left channel after uploading to YouTube

[Longboardluv]

I have an ongoing issue with Corel videostudio. basically I'm filming a vlog using a GoPro Hero 7. I edit the whole video add music to it. And upload it to YouTube. But the problem is that all the audio but I'm using during speaking is only coming out of the Left Channel. This is become very annoying. I know that there is a technique to duplicate audio from one channel to the other. But I don't want to have to do this for every video. Do you have any idea what could be causing this issue? It doesn't seem to be only coming out of one channel when I play the audio and the video on my computer. But when it gets into YouTube it is only coming out of left Channel. The weird thing is the music that I've added to the video comes out of both channels. Any help at all would be greatly greatly appreciated

The gopro 7 record only to left ?

No of course not. It records both channels. It's very strange because the video itself when I'm playing it on my computer in the program it sounds fine it comes out of both channels.

Hi
Uploading to YT we have three options
1 / render the project to a video file then use upload file
2 / upload the project that will render the project then upload
3 / create the video file and use our YT account to upload, not Video Studio.

If you use option "1" you can play the video to check the audio stream.
You will then know if it is the render process, settings may be wrong or the upload process.

What are your project properties?
Do you know what settings were used to create the video file.
