Using Invoke-PnPSiteTemplate breaks Document Set Shared Columns

I have a template site that I use that contains custom content types that are Document Sets. These Document Sets are configured with Shared Columns that should propagate to all files uploaded in the Document Set. When I apply the site template to a new site the content types are created but the shared columns do not work. They do not get populated when I upload a file.

It also breaks shared columns for all Document Set content types on that new site. After creating the site and applying the site template, I created a new document set content type and added some shared columns. They did not get populated either.

I verified on all document set content types that the settings were correct after applying the site template. So it appears that using Invoke-PnPSiteTemplate on a site breaks the Shared Column functionality for the entire site. I have tried with PnP.Powershell version 1.12.0. and 2.1.1

I am running out of ideas on this one. Could someone please look into this. Thanks.

Start by reproducing the problem with Invoke-PnPSiteTemplate using a template containing Document Set content types and shared columns. Compare shared-column behavior before and after provisioning, including for a newly created Document Set content type; done means shared columns propagate to uploaded files on the resulting site.
