I've had the same thing happen, reported it twice with details of which furnishings, and never heard back, not even a confirmation that they'd received the report. When I've reported other things I've alway heard back.
It's happend a few more times since, usually doing daily endeavours fast. I isn't even bother reporting it now, even though it's extremely exploitative, as it seems they just don't care.
For at least some of the furnishings I know it definitely didn't pull them from the vault, as I only had one of them before the duplication glitch.
