XR15 remote wont control TV

Just installed a new Hisense-Roku flat screen (yeah a cheapy).  I can get the XR15 remote to control the volume and channel no problem.  However, the XR15 remote will not work to move the choice from the "Home -->" screen to the various apps (suce as cable, prime, netflix) that are presented at power ON by using the arrow buttons. 

Using the codes sypply by xfinity for the Hisense TV does not work.
