Hello Tracey
Thanks for getting in touch with us.
We’ve just tried to replicate it locally and it works properly on our side.
However, I think there was some trouble with uploading the images. Please, do you mind attaching the images again, so we could try to find the best solution to the issue?
Although, if you want to add inventories manually, make sure the option Auto-assign inventories to WC Orders is disabled.
You can disable it by going ATUM Inventory > Settings > Multi-Inventory > Auto-assign inventories to WC Orders.
Best regards,
Iryna
