After adding one variant to a product, all of the previous variants have been deleted.
- Vend for Mac or PC
This occurs when a new variant is added incorrectly. Instead of adding a new value (Green, Blue, Big, Small) an attribute (Color, Size) has been edited. Because all of the previous variants used that attribute, deleting it causes all of the previous variants to be removed.
If you have backed up your products recently via a product export, importing the rows of the CSV pertaining to that product should resolve the issue.
Otherwise, submit a ticket to Vend support and one of our friendly support agents can help you with resolving the issue.
