Zero Hop Counts

Hello all. I have a BIG-IP 6400 running version 9.4.5 HF2. When I go to Main>Statistics>Global Traffic then select "Paths" in the Statistics Type drop down I receive output, but the "Hops" Current and Average numbers are all Zero's.

 

I have checked the metrics collection settings and they are all at their defaults. I thought I might be having a problem with the statsd daemon, but I have valid performance graph information under the performance tab.

 

Any ideas as to why the hop counts would show up as zero?
