There seems to be no way (that I can figure out) to add a 'new line' to a page of text.  Minecraft doesn't allow blank lines, but does allow you to press enter once to go down to the next line (a 'reset' formatting code can then be put all by itself on a line to simulate a blank line).

This should give you the next line. You need to double up. It's yaml causing the problem for you not the plugin.
- 'L1.
  still L1

  L2.'
- 'Page 2, L1

  Line 2'
