The plugin this refers to is “New User Approve”
I was under the impression that I created a Support Topic in the Forum section for this plugin, not a general one.
I use “Loco Translate” to show (and if needed, edit) the translation files that all plugins use. It shows all of the .po files and also the .pot templates.
The file in question where one placeholder is wrongly capitalized is “new-user-approve-de_DE.po”
