Good question, @nekojonez. It’s a bit ambigious without knowing the context. We actually no longer use this particular string (it was used during development for our latest version, but got dropped in the final build) so it should have been removed. I just removed it so it should disappear when the next update drops. Please feel free to ignore it in the meanwhile.
Vriendelijke groeten uit Brugge 🙂 en bedankt om AIOSEO te helpen vertalen!
