I've tried everything, but it hasn't worked!

I deleted and removed a custom metadata field, and there's no longer images associated with this custom field. I even made sure it doesn't appear as viewing option on my metadata viewing fields under the info tab.

My problem here is, it keeps appearing as a field in my info tab metadata info. There's nothing checked and theres no longer a custom field with this particular name. I imported a new batch of images, and even these were assigned this field.

What can I do to stop this field from appearing? ~ Thanks!
