Sk typo in translations file for key Outlinks. In SK there is no "Konkajšie" but Vonkajšie. Word mens outer or external.
Thanks for the PR @branislavballon . We don't manage translations here in Github unfortunately and can't even merge it since it would cause issues :(
Our translations are managed through a system called Transifex. If you're interested in changing translations in Matomo be great if you could go to https://matomo.org/translations and reach out to us via this page. We can invite you to our translation system.
