Can't use Quick Edit to change page to Sitemap template

Hi. Just to let you know that changing the template to Sitemap is not working for WordPress 4.5 when using Quick Edit.

It works fine if I enter full Edit mode and change the template there.

Using Quick Edit I keep getting the “Are You Sure You Want to Do This” error and can’t save the changes.

By the way, is there any documentation on how the Sitemap template actually works? I couldn’t find any at cyberchimps.com.

Cheers.
