Hello all,

I hope this doesn't seem too trivial but I am relatively new to Network Analyst.  The reason for my post is that I am having issues with holes appearing in the service area polygons near a facility that seems like it would be within the "actual" service area.  I have attached a photo to show what I am talking about.

Is there a way to fix this and/or why am I seeing these holes?
