I’m developing a plugin for Shopware 6 that extends the product specifications tab with additional fields. The data is loaded correctly when data is manually inserted into the database tables (wuc_catalogue_box_extension and wuc_catalogue_box_extension_translation). However, when there is no existing data, the administration interface does not allow me to input and save new data. The data appears to be initialized correctly, but it is not being saved to the database when I click the default save button of the product editor in the sw6 administration.
