That still wouldn't cause this problem, as you can see from the cat, the contents of the file are correct.
No, the contents of cat show 75 visible characters. There is a single line break, which should add up to 76 characters if it's Unix style LF, or 77 if it's Windows style CR+LF or any other kind of "invisible" character is somewhere in these two lines. If it is somewhere in the first line, you'd be getting "Not found" error.
