VS code lines and multilines

I have a problem with vscode. Wen I type something in few line lines and press CTRL+S everything changes to one line.

• Example:
  1. Some text
  2. Some text
  3. Some text

and after that I press CTRL+S happened this: 1. Some text 2. Some text 3. Some text

How can I fix that to stay in few lines after I press CTRL+S?

Sorry on my english still learning :)
