Why is my document not showing the correct spacing after a line break?

1. Check the font size of your document, and ensure that the size is large enough to clearly see the space between lines.
2. Check the margins and boundaries of your document to make sure that the spacing does not interfere with the normal flow of your document.
3. Ensure that the line breaks are properly inserted at the end of each line.
4. Try utilizing a different font type or size to make the spacing more apparent to the human eye.
5. Do some light testing by introducing different types of content and spacing, and observing the results.
