I hope you are well. Welcome to the community, congrats on your first post here.
From looking at the account in question, I can see its on the legacy pricing model which is what is causing the issue. Its a pretty simple fix, please follow along Switch to the new pricing model | New Relic Documentation.
I would also advise you to consider migrating the users over to the New Relic One Model, Migrate your users to the New Relic One user model | New Relic Documentation .While this is not required currently. It is always best to be on the most current model of things, in my opinion.
I hope this was helpful, please do let us know should you require any additional support!
