Razer Controller App missing buttons for assignment

Hey all, I used the Razor Wolverine Tournament Edition about a year ago and decided to get another one after my Elite Series 2 broke. When using the Synapse software (same on Xbox and PC), it required an update. So I let it do it's thing. Upon updating, there is no button mapping/remapping for the Back Button or the Start/Menu Button. One of my main purposes for this controller was to map the Back Button. Does anyone have any possible workarounds or know when Razer will put back in the missing features the it USED to have? These are the only two buttons missing from the button-mapping menu..
