"br" phoneme is silent Unless I put an "cl" before it?

Hello! Nice to meet you, I am kinda new there.

I have an issues (I do not know if it is really an Issues) that is bugging me out with Synthetizer V Studio pro (I use the latest version 1.7.0).

When I put the “br” Phoneme before a note, It is silent. But if I put “cl” before it, The breath is heard.
The same thing happen if I put the Note containing the “br” phonemes in question in a separate track.

I should note that not every voice have this issues, But I mainly have this issues with kevin.

Hopefully someone can Give me an explanation and workaround. Thanks for reading.
