I've found that if the metatag module is enabled and you try to manage a "node edit form" then the node title field is missing. I've defined the priority to major since it makes impossible to use this module on node forms.
Here is the information displayed at rel-register/nojs/article_node_form . There is no other "fields" with a "title" machine name
Element: "Title", Machine name: "title", Group: "Meta tags"
So the origin of this issues seems to comes from the _rel_recursive_elements way of flattening the form elements. Maybe something like this would be a good start:
if ($parent) $key = $parent . "_" . $key;
But I've no ideas of what this can implies (and even if it's remotely correct).

ryan.armstrong CreditAttribution: ryan.armstrong commentedI can confirm the same behavior. This module is incompatible with the Metatag module.

to avoid having title field not show due to conflict with metatag module--just don't check the title field during 'manage form display'.
Then afterwards you should still be able to control title from 'manage field display' page.
