Issue: 

Page detail "Created at" is not visible if the page link field is hidden.

Steps to reproduce:

• create a new DB

• add a tag column if it doesn't already exist

• in the tag column, create a tag and insert it into the first entry

• add page link field

• insert the page in the first entry of the page link field

• add page details field

• set page link property to the page link field you just added

• set displayed detail to "Created at"

• change the layout to "board"

• in the hidden fields menu, check the page details field

• save the view and make it the default

• refresh the page

the page details will not be shown. this is a bug. if you return to the hidden fields menu, and check the page link field, it will display both the page link and page details field.
