Custom field still appearing in Jira Rest API even after deleting it via Jira Admin

[Oscar]

We've already deleted a custom field via Jira admin but it still keeps on appearing when we're trying to get a list of custom fields via Jira Rest API.

Does anybody encounter the same issue and came up with a resolution?

I think that by default field is going to trash first and would be removed after 60 days. Please take a look on this documentation and check if that is the case

If so you can remove it permanently, but of course you would not be able to restore it later.

It's no longer in the trash, actually. So I would assume it's totally removed now. But still, it's appearing in the Jira Rest API list of custom fields.
