Rendering bug on Davinci Resolve 15?

Hi there

I am new to this form and not a professional by any means. Not sure if the below issue is a bug or a user error? I was using Resolve 15.0.0B.043

As you can see, the waveform is totally fine in the clip, preview in Resolve confirmed the audio was good. However, after I rendered the clip, my voice is distorted/clipped yet the music is fine.



Here's the clip
/watch?v=QECIn_EDvkU&feature=youtu.be


Your help is highly appreciated.
Thanks

I have just noticed for the post, thank you.

It is unfortunate that I cannot post a URL directly. The link is:
youtube.com/watch?v=QECIn_EDvkU&feature=youtu.be

Your brower would problaly complete the Wx3 times and a dot for you.


Remark:
Audio 1 = voice recorded directly from Panasonic G85, AAC file
Audio 2 = music downloaded from interner, mp3 file

I think I have figured out what's going on.
I have normalized the audio 1&2 to 0dBFS with some level tweaking/mixing, then raised the level of the main level of the mixer to problaly +10. After the clip was rendered, the audio was problaly "overloaded" and led to clipping.

Even though it sounds stupid for such user error. I would like to point out for the below:
1. There was no warning for such stupid action.
2. The change of main level does not affect the waveform, thus users cannot find out the problem in real time.
3. There was no clipping when preview.

Thanks.
