Declined Title Deletion: Removing obsolete 'imdb display title' attribute

https://contribute.imdb.com/contribution/261011-095421-213000

Hello. I am trying to fix a title attribute error. The database currently has an old/incorrect attribute on this movie page: an obsolete '(Soviet Union) (imdb display title)' without a specific language tag.Following the system prompt ('not possible to correct this item directly, delete it and add a new item instead'), I successfully added the correct title in Cyrillic with the proper language specification: '(Soviet Union: Russian title)'.However, my contribution to delete the obsolete and redundant old attribute was declined. Since the correct title with the precise language tag is now live, the old one is incorrect and needs to be removed to avoid duplication. Could you please help approve this deletion? Thanks!
