I'll take a stab in case you still aren't sure:
I'm pretty certain you have 2 "3rd Edition" printings. The older, on the bottom was manufactured in April 2012, while the newer one was manufactured in March 2013.
The latest print of the 3rd Edition was done in February 2014, which was available via Kickstarter and is the copy floating around now.
The actual 4th edition is supposed to arrive "late 2015". That will be a new edition with new artwork, etc.
Thank you. I forgot to update this thread but shortly after posting this I decided to email the publisher and got a response right away.
You are correct though, they were both 3rd edition printings, just different dates/print runs
