"ignore" option of codecov.yml is not working

I set the following ignore options on my “codecov.yml” files.
However, those files are still shown on my report in “https://codecov.io”.
Does anyone know what is the problem?

ignore:

  • path1/path2/path3/file_name.go
  • path4/path5/path6/file_name.go
  • .*/aaa.go
  • .*/bbb.go
