Model Re-targeting Fail

So I followed this guide here because I wanted to use the animations offered to me on my model but I had a different skeleton.

** Guide

I followed the guide completely

** Re-Target Manager on TP-Skele
** My Skele’s Re-target Manager

but ended up with different results. After I duplicated and re-targeted the animations from the Third Person Skeleton, I went back to my characters folder and noticed the animations were missing their mesh.

** Missing Meshes

I went into the Persona and tried playing an animation but when I double clicked on an anim, my mesh disappeared.

** Animation Persona
** Mesh Disappearance

So I am wondering what I did wrong, I assume it has to do with inputting the wrong bones in the Re-target Manager but there’s bones I don’t know which are which in my mesh because of using Riggify in Blender to ease the rigging process.
