where to turn on author info for flexinode

I just installed flexinode on 4.7.0b6. How do I get the author field to show up? There is no choice to add an author field? It doesn't show up on the node. I need to use the actual default Drupal author field (not just create one) because I am using tagnode to link it to the author's Drupal profile field. Similarly, how do I make the date submitted information show up?

The author and date fields are enabled for all nodes and show up on all other nodes.

I checked settings in admin, flexinode, content types, and themes.
I read the readme and install files.
I searched on this site, but people were asking how to add multiple authors, and non-registered authors. It seemed they knew how to make the author field appear.
