Stockable variants not Saving

[sucuisine]

Hi
I am using VM 2.0 10

I have created a custom field of type Plugin and when I select the plugin Stockable variants, enter the Options and values and click on Save, the Option and values disappears-> is not being saved.

Who can help me with this? I read a lot of threads in which they are using stockable variants, but still did not succeeded in saving it.
