Set-SPOProvisioningTemplateMetadata strips out the Providers tag from the provisioning template

Hi there,
 
I've discovered that when I execute Set-SPOProvisioningTemplateMetadata to set the Template DisplayName property, it strips the Providers section from the template.
 
The template validates against the schema matching it's version.
 
I'm attaching what the XML template looks like before and after executing the commandlet.
 
Please help.
 
Thank you,
Jan
