On variant definition, on variants tab, the field for the variant price ('Operator Store price') cannot be edited.

Way to reproduce:

• Having actual CoreShop3 version with pimcore 10.2.3 installed
• Having class CoreShopProduct - enabled inheritance and variants, and showing variants in tree
• Defining variants iE TShirts with color/size as products
• in variants-tab - adding in grid options: Others - CoreShop - Operator Store Price
• preview shows defined store-price (StoreValues) variant price in grid definition
• 'Save and share' grid options
• field 'Operator Store Price' is showing defined variant price in grid
• clicking on field 'Operator Store Price' - shows popup with error: This element cannot be edited
