I think I have an idea of what's happening here!
@707 mentioned recently restarting, so...
This is most likely related to the Project K storyline, when the villagers ping you to help bring K.K. over and give you various things to help!
IIRC, there were also Nook Miles furniture from your variant pool and customised DIY items in the pings, which is also way out of the ordinary.
So this would be a 'plot-related' thing that happens once early on if you happen to catch it and that's it. Just my speculative two cents!
