IPN returns DISABLED but profile shows ENABLED

[HolyMoley18]

Something I haven't experienced before, so I'll ask here:

For a client I have IPN set up. It's enabled and I've tested this by sending a payment to the recipient through IPN.

The payment goes through fine, but it's also telling me that the status is "DISABLED" instead of "VERIFIED".

What do I need to do here to get it to say "VERIFIED"?

Thanks
