New Pleskian
Somewhere around the arrival of Drupal 8 the possibility to choose language seems to have been lost in the automated installation procedure provided by Plesk.
Installation using installation language is against Drupal's recommendations for multilingual sites: Choosing and installing multilingual modules .
As a matter of fact, adding a language and setting it as default can cause problems in Drupal core modules such as Admin, Contact and Views for mono-language, non-English sites as well.
Should this problem prevail in Plesk, I would recommend manual installation with Drush/Composer/Git or else switch to a more Drupal-friendly server administration panel tool.
