I changed Theme and Server and field data disappeared

Hello, I have a jewelry store online, I have created a custom field for people to add the children’s names.
I recently changed theme and server transferred and everything went right but the custom field name disappeared, looks at the database in the wp_woocommerce_order_itemmeta table and the data is inside it, but does not show in Orders in?

How do I re-appear?

Thanks a lot for the help.
