Problem when edit prouduct.

Hello.

if I import a product with variations for EX: Colors and Size and just click in Edit product then save/update without any edit. all attributes will delete. attached pic before and after clicking edit product

plz help asap as this is a critical issue I can not edit any product

Am using Theme’s SWATCHES Flatsome Theme but anyhow I turn it off and return it as default and the issue remaining, I test to add manual product with variations and no issue with it I can make any edit and after the update all variations there, but any edit in product imported using the dropshipping plugin all attributes removed as I show you EX above.
