@Raymundo Castro Thanks for the question. we would recommend to raise a Azure support desk ticket from Help+Support blade from Azure portal for your resource if you have a support plan for your subscription. This will help you to share the details securely and work with an engineer who can provide more insights about the issue that if it can be replicated. We are able to see the culture as shown below.
