Thank you, but this is a source issue: https://docs.fedoraproject.org/en-US/fedora/f27/

Correct process is:
Click on "edit this page" on top right of the page.
It will lead you there: https://pagure.io/fedora-docs/release-docs-home/blob/f27/f/modules/ROOT/pages/index.adoc
Then open a PR
Next time I'll update the pot, it will automatically correct here.

If I accept this PR, it will be erased at next update

Ok, I opened a pull request there. Thanks for help.
