I am space administrator, and I created a template called "External One Pager" and promoted it. However, when I click "Templates" menu on top bar, I see 130 built-in templates, but do not see the one I promoted. Where do such promoted templates show up?
When I create a page, it does show the template I created (see screenshot below), among a few more built-in ones. Is there a way I can hide all built-in templates and always have only promoted ones to show up, both in "Templates" and also when they are creating a page?

Thanks
