Locator and exported tracks

I have added 3 tracks. When I try to define locator and choose Edit > Select > Start from cursor and press P it will not export defined locator. Is this the correct way to export defined tracks as it will not be exported.

Yes, maybe I have an issue with the basics as I test only audio quality, but I read locators and function. As I understand I have to select ALL and click P to activate locators. But when I choose Export it will be without voice. I’m not sure if there is some trick as voice is not heard but tracks contain voice.
