In my default layout (admin/structure/layouts/manage/default), when I go to add a visibility condition to a block, I don't see an option for "Content type" in the dropdown. Instead I only see "Home Page", "Site Language", "URL Path", "User Permission", "User Account: UID", and "User: Role".
According to another forum post this should be available - https://forum.backdropcms.org/forum/ill-show-you-block-only-page-i-want-how. Am I missing something obvious?
This is for Backdrop 1.25.0.
