I wondered that myself, something must have been duplicating for all but one to get denied? I can't believe even that manufacturer would reuse the same MAC but whatever it was I guessed they're all sending but only one was getting a reply.
I assumed they had maybe a proxy set for their corporate network they'd forgotten to untick or something.
I couldn't see how, I'm using Connect on android. Searching settings for "language" didn't show any results.
I did find "blocked instances includes comments" though, I've toggled it off and will see what happens.
