Trying to use Panelizer for a node content type with a panels layout
Panelizer 7.3.1 Panelized content shows in preview, but when I view the live page, it looked like a regular, un-panelized node.

Turned on and off everything I could think of...

Finally, I looked at the Display tab of my content type, and clicked open the Custom Display Settings. I turned OFF "use custom display settings for view modes: Full Content and Teaser". Suddenly my nodes were panelized. Click back on "Full Content", and panels disappear.
