When editing a migrated video, the MARC fields are loaded using internal schema keys (e.g. tag_964) instead of the expected numeric format (964). And this was causing Validation error.
See:
tag_964
964
Added @pre_load hook to normalize tag_XXX → XXX before deserialization
Added @post_load hook to convert internal tag_XXX → XXX after deserialization
