Want to change my name on Trazzler, which is stuck on my facebook name...

Hi guys, so I initially wanted to switch my facebook accounts from my social facebook to my professional facebook via the facebook syncing with Trazzler. That appears to have worked, since I believe I was able to sync up my Trazzler account with my professional facebook account at this time. However, Trazzler still appears to be stuck on my social facebook name, rather than my professional facebook name (aka my real name). How can I switch my name on Trazzler to the name matching my synced facebook? Thanks!
