Dear anonym,
Based on your screenshot, it is the data retention setting for your current active user that you selected.
For the deleted user, suggest you raise a support ticket from the Office 365 admin center, where the related team will check the data retention setting. Reference: Get support - Microsoft 365 admin | Microsoft Learn
Note: To create a support ticket, you need to have admin privileges and if you aren’t admin of your Office 365 organization, please contact the admin of creating a new ticket.
Thanks for your patience and understanding. Have a good day!!
Best Regards,
