Microsoft.Compute/virtualMachines/extensions' has incorrect segment lengths

I'm unable to deploy this NESTED template because of an Custom Script Extension (CompDesc) that I've added to it. I am prompted with the following error when trying to deploy:

Error: Code=InvalidTemplate; Message=Deployment template validation failed: 'The template resource 'CompDesc' for type 'Microsoft.Compute/virtualMachines/extensions' at line '207' and column '6' has incorrect segment lengths. A nested resource type must have identical number of segments as its resource name. A root resource type must have segment length one greater than its resource name. Please see https://aka.ms/arm-template/#resources for usage details.'.

As you can see it already has a DSC extension which I have tested and deployed perfectly fine, but I also need to add this CSE for a small .ps1 script.

I have checked out: Azure website resource template error and Set ARM Template Web appSetting

I have tried:

I know it has something to do with the naming convention, but I'm unsure on how to fix it. Bear in mind, that this is a nested template. From what I read and understand from the error, nested templates must have identical segments as its resource name, which I've tried.

Please, any ideas?

My god, an oversight by myself. I forgot to re-upload the nested template to blob storage once I made my changes. So dumb.

Anyway, for those that want to know; https://github.com/blumu/azure-content/blob/master/articles/resource-manager-common-deployment-errors.md
