Can't delete App ID from Apple Developer Center

I've seen where Apple has changed the Certificates, Identifiers & Profiles page of the iOS dev center, and read this question/answer here on stack: Removing App ID from Developer Connection

But I'm unable to delete an App ID/IDs that are several years old that I would like removed. The 'Delete' button is greyed out/not enabled.

Can someone help me at all? I've tried multiple browsers and clearing my cache to no avail. Thank you in advance!

Can T Delete app ID from a deleted app?

App IDs cannot be deleted once used in the store. Deleting an app doesn't free up it's app ID. You may have a problem, tho, considering you've already deleted that app.

The rule is that if an App ID that has ever been submitted with an App to the store, it cannot be deleted (even if it was not accepted). App IDs that have not yet been used to submit apps can be freely deleted.
