Delete empty line

Hi,

When, at the start of an empty line (break);

1. If I press backspace, it won’t delete the previous line.
2. If I press delete, it won’t delete the line I’m on.
3. I have to go at the end of another line and press delete to delete the next line, and this does not always work.
4. I’m just trying to delete an empty line, why is it so difficult?

There is no configuration or formatting or a type of character before or after or whatever else that should make it impossible to delete a simple line.
