Linked copy: imposisble to export/import a template which was not initalize a first time on a cross-site linked copy

I am making a cross-site linked copy the "Socilété" section of the packaged demo on a second site. The second site is only using the home and simple page for the moment.

The first linked copy worked fine. Then I added some new page in this section such as some "publication" template, etc... Such page are not imported correctly on the second site while creating another simple page works

It looks like template which where never instanciated first on the second site are not correctly imported.
