Looking for Complete reference application / schematic of STWBC86 Wireless transmitters

Hi I plan on using STWBC86 for a wireless charger prototype. I was looking at the datasheet for the reference designs and found that the reference schematics has missing or has hard to read values, labels, and wires. Is there a better version of the schematics that is clear and completed? 

If there is not, can anyone give recommendations for the highlighted parts?

I have also attached the original Schematic as a PDF below so you can see the clean version as well.
