I try to load Template when creating a page, but nothing happens

I’m trying to create a sales page on my website, so I go all these ways:
Page> New Page> TagDiv Composer> Load Template> selected Product Loop – Kids Store> Click Import Section> OK> And the requested change does not appear, that is, the Kids Store Template does not appear.

How do I activate it on my page?
