The suggested player count listed for each minigame or world template (adventure, experience or inspiration) in Realms is not translatable.

There are four types of player counts:

• %s player
• %s players
• %s+ players
• %s-%s players

The language in the attached screenshots is set to Italian, which has been 100% translated on Crowdin. The above strings are missing from the language files and thus are untranslatable.
