Expected or Desired Behavior

Template should get extracted and applied without errors

Observed Behavior

File not found error

Steps to Reproduce

I am using the latest version of PnP version 3.1.1809.0 to extract a site template (PnP Powershell) from modern team site. While applying the template to another site (PnP Powershell and sites-core both), I get a File not found error.

On setting the trace log, I see the log file that the application fails at a step "Updating field 1a53ab5a-11f9-4b92-a377-8cfaaf6ba7be"

In the template I see that a tag has been added for each list instance for the field "_DisplayName". On removing these tags, the template application works well.

I saw the templates extracted from earlier versions of PnP and I cannot see this tag. What is the purpose of this tag in the list instances ?
