How to delete subscriptions group in itunes connect

I am in trouble, I made a test subscriptions group in iTunes connect, but now I cannot delete it. Is there any way to delete it?

Can you delete Subscriptions on iTunes?

Tap your Apple ID at the top. Tap View Apple ID and sign in if prompted. Tap Subscriptions. Find and tap the subscription you would like to cancel.

How do I delete my subscription history on iTunes?

You would not be able to delete your Subscription History, just as you cannot delete your Purchase History tied to your Apple ID. Both will always be associated to your Apple ID account, and accessible within your Settings.

This does not currently seem possible.

From this thread on the apple developer forums:

No, those are required in situ [on site] for historical reference and to help guard against duplicated/conflated references going forward.

Feel free to file a feature request via the bug reporter link, below right, if deleting them is something you'd like to see in the future.
