Im really not sure, what's happening, also im going to provide two things here:

1./
First of all i believe 'Hide label in node listings' makes no sense as we've got the 'content type / Manage display / Full Content' setting (that we can get when setting 'content type / Manage display / Custom Display Settings).

So 'Hide label in node listings' makes no sense.

2./
I set two content types to hide titles also set Full content settings to hide titles.
None of their titles are hidden in node listings while one of them show title on teaser display the other doesn't.
Im very busy, I'm not going to take 5 hours to figure out what causes second bug especially because what mentioned in first point makes it not necessary.

Also I'm very happy to mention that i'm glad because of the existance of this module and thanks for all of your effort as this modules aim is brilliant, finally it will solve a basic issue of drupal.

Regards
