Hi,

How did you add/edit variants? Is it via Shopify admin UI? 

Sounds like when you edit variant - some values are either not populated or got overwritten.

If you're doing this va Shopify admin's product variant screen, suggest you carefully review/compare the two scenarios and see if there're critical values (e.g. variant option value) are missing in the edit case.
