All charts apps need to be terminated before the project can be deleted

I wanted to delete the organization in my MongoDB account but when I try to do that, MongoDB forces me to delete all the projects first. I deleted all my projects except one. When I try to delete this project, a pop up appears like this

But even if I terminate the cluster and delete the charts, I'm unable to get rid of this pop which is preventing me from deleting the project. You can see I don't have any charts here Nor do I have any clusters

I got the same issue I deleted the project using these simple step..

• In project dashboard click on three dot icon which is left of delete icon.
• Click on "Visit Project Settings"
• Scroll down to the bottom
• You will see an option "Delete Charts" click on red Delete button
• Come back to project dashboard and now you can delete it without any error
