Export and Import SharePoint site using Get-PnPSiteTemplate & Invoke-PnPSiteTemplate will not preserve the value of the people/group field

[mvcsharepointdev]

I have a SharePoint source site which contain a People/Group field linked to a SharePoint group named "Level2", as follow:-

now i export the site using this powershell:-

Get-PnPSiteTemplate -Out "c:\users\mo\site.xml"

then i created a new site, apply the template using this powershell:-

Invoke-PnPSiteTemplate -Path "c:\users\mo\site.xml"

but on the destination SharePoint site this field will be linked to all users instead of been linked to the related group (Level2), although the Level2 group was imported successfully. any advice, how to preserve this setting?

Thanks
