Custom Metafield definitions - error

I am experiencing the same issue. 

I checked the network API call and it shows the following error, screen shot also attached.

{
"message": "Variable $input of type MetafieldDefinitionInput! was provided invalid value for copyToOrder (Field is not defined on MetafieldDefinitionInput)",

@agiledigital I tried it again. It's working now. Hope it works for you too.
