Remove app failed even after removing all in-app purchase

Our team was asked by the Apple team to remove our old app in order to submit the new one(same app). But when I clicked the remove button(already removed all in-app purchases items), it still showed the same error message: You need to remove all in-app purchases before removing the app. Can anyone help me with this issue? Deeply appreciated:)
