I was able to solve this issue. For any beginners out there, just so you know, the GUI Touch Event action can be used for Multi touch as long as you use the finger ID option. However, one touch will always take priority over another. So in my case, my Dpad and jump button worked great together, but my Dpad had priority (lower finger ID value). So I couldn't use my jump button by itself. It relied on the Dpad being pressed in order to function.
To fix this issue, I downloaded Touch Script, a free open source plugin off of the asset store which has Playmaker actions built in. Touch Script works great for Multi touch and with a little adjustments, I was able to convert all of my buttons to work with their playmaker actions.
Long story short: if you need good multi touch, download the Touch Script plugin from the asset store.
