How do you remove blue lines from a word document?

[Grace]

I am updating a word document with bullet pointed list and normal paragraphs.
The document alrealy has some blue lines that might indicated previous
breaks, in it. I need to remove these but can't seem to delete them
successfully. How do I achieve this?

It's possible you're referring to tracked changes. You need to accept all
the changes. How you do this depends on the version, which you have not
stated.
