I'm not sure if the Title Display module is relevant for your issue. I was however stumbling upon these statements:
- Title Display only affects the placement of the Title in the content creation form, not on the display of the node
- There are no settings for Title Display, so the behavior is the same with or without it
The Title Display settings are indeed not easy to find, or at least there are several places to consider. And if you combine them, Title Display does affect the placement and behavior on content display.
- In the vertical tab "Title display" of the Content type configuration form (e.g. admin/structure/types/manage/post) you enable the "Title as a field" for the desired display mode(s). Note: This doesn't work for the Default display mode, but you can use the "Full content" mode instead.
- Still in the vertical tab, open the collapsed fieldset of the Display mode(s) chosen above, select a HTML tag and enable or disable the option "Link title to content".
- Go to "Manage displays" (e.g. admin/structure/types/manage/post/display), click "Manage Display" for the relevant display, e.g. Teaser, and move the Title 'field' to another position.
