Unable to create a page without header / banner webpart

I am trying to create a template with pages without a header. So I create a page, remove the banner webpart with the section. Save the page and publish it. All is fine. Then I create the template with PnP.PowerShell (Get-PnpSiteTemplate -Out teplate.xml -IncludeAllPages).

When I then invoke the template again, my pages will have the default banner webpart again on the page.

The XML created for a page without header will have this block:

<pnp:Header Type="Default" LayoutType="FullWidthImage" ShowTopicHeader="false" ShowPublishDate="false" ShowBackgroundGradient="false" TopicHeader="" AlternativeText="" Authors="" AuthorByLineId="-1" />

The result will look like this:

Removing the header line in xml will result in something like this (same goes for a header with type = None):

It should look like this (no banner at all):

Some additionally information:
PnP.PowerShell Version: 2.99.175-nightly

Having the same problems using the current release of PnP.Framework Nuget package (1.17.0 with PnP.Core 1.14.0) in C#

Start by reproducing the issue with PnP.PowerShell using Get-PnPSiteTemplate -IncludeAllPages, then apply the generated template and compare the page Header XML with a page that has no banner. Trace the PnP.Framework provisioning path that reads and applies the pnp:Header element; done means pages without a header remain without the default banner.
