Hi Katrine,
Do you use Allocation Plans? If the inventory was correct after the sale in SixBit, that should have ended the Listing. Also, in Options, Inventory, which option is selected for Insufficient Inventory? Make sure it’s not the “Create a purchase record…” option. If that’s not it, open a ticket with support and we’ll be able to follow up with you directly.
Thanks,
