Display Suite module is not displaying field labels I am using the Display Suite module (version 7.x-1.9) and Drupal 7.37. 

I selected above or inline in the Label column for all the fields, but I don't see the labels on my page for any fields.

I also don't see the display suite tab when I try to edit the page. If I want to change the layout, I have to go to admin > module > ds > configure to change the layout. 

Can anyone help me workout what's happening?
The page you see is from the "Default" Manage Display. Make sure you use this instead of others. The Display Suite layout is based on per content type, not per node. To change the Default display, you should go to "Structure > Content types > Your content type > Manage display" or "Strurture > Display Suite > Manage display(your content type)".
