Translation included in Crowdin does not appear on yml

The string with this context root -> decidim -> participatory_processes -> participatory_process_groups -> none does not appear on the file partecipatory_processes/it.yml and is required. Crowdin shows the string, which is maybe inside another yml file (see screenshot), while the GUI shows an error for a missing translation (see screenshot). I don't see any other error of this type on the GUI. Please, take into account that we are importing locales manually copying ymls on the gems, check https://github.com/decidim/decidim/issues/5219
