Templates dropdown not appearing in New Page screen

When I click on “New Page” in the left menu, there is no place to select ANY template in the“Page Attributes”-box on the right.

If I click “Quick Edit” in the list, however, the “Template” drop-down is visible – but the only thing in it is “Default template” – not my custom template.

These are the first 5 lines of my page template file, which is under Content/Themes:

‘
<?php
/*
Template Name: BluesD_1
*/
?>
‘

So I have 2 problems:
1. Not seeing any template selection options on the New Page screen
2. Not seeing my custom template in the template selection dropdown under Quick Edit.

How do I make the page template choices drop down appear on my New Page screen?

Thank you
