No Season 7 episode 8 on Outlander

I signed up to Starz on Cox so I could watch the newest episodes of Outlander.  But there is a problem.  There is no episode 8. It jumps from Season 7 episode 7 to Season 9 episode .  Cox has all the rest of the    episodes except 8.  I contacted Starz but they said this is a Cox problem.  Please direct this to the proper person at Cox Comm Omaha and get this rectified.
