Now it is rendering all 4 pages. Close this issue maybe.

There's overlapping text/fields on the first page, possibly related to all of the font warnings:

config stream contains a map for font substitution:

<fontInfo>
  <embed>0</embed> <!-- 0|1 -->
    <!--defaultTypeface>MyriadPro-Regular</defaultTypeface-->
    <map>
      <!-- [0..n] Attributes: from='', to='' [0..n]  -->
      <equate force="0" from="Courier_*_*" to="Courier New_*_*"/>
      <equate force="0" from="CourierNew_*_*" to="Courier New_*_*"/>
      <equate force="0" from="Courier-New_*_*" to="Courier New_*_*"/>
      <equate force="0" from="MyriadPro_*_*" to="Myriad Pro_*_*"/>
      <equate force="0" from="MyriadPro-Regular_*_*" to="Myriad Pro_*_*"/>
      <equate force="0" from="MyriadPro-It_*_*" to="Myriad Pro_*_italic"/>
      <equate force="0" from="MyriadPro-SemiboldSemiCn_*_*" to="Arial Narrow_bold_*"/>
...

This pdf doesn't contain any fonts.

We should probably always fallback on the fake myriad when the font isn't available.
