  • I have the same issue. This problem only occurs on some products.

    Hello wesolowski,

    Thank you for your reply. Do you have a fix for it?

    Kind Regards.

    No, I installed ATUM Stok Manager and it’s working fine

    Hi De Belser Arne,

    Apologies for the inconvenience.

    In the video, I can see that product type is blank. Can you send me product type of the SKU you are trying to edit? I’ll check and let you know.

    Hello @storeapps

    Thank you for your reply.

    The product type of that SKU is “Variation”, it’s part of a “Variable” product.

    The one I affichiate in my video is one “Variation”. Hope that clarifies, if not let me know!

    Thank you for the confirmation.

    Have you renamed/translated Variation/Variable to something else? Because it is working well on my end.

    If you have renamed/translated, please share what you have renamed/translated to and how you achieved it?
