Problem with Service Area analysis results appearing as broken, jagged areas (ArcGIS 10.5): I ran a Service Area Analysis for locations across the US using 8 different time increments. The analysis runs fine for most of the country creating roughly concentric service areas for my different time increments. However, in certain areas like Kansas, New Mexico, South Dakota, Seattle, and Illinois the service areas come out as jagged and disconnected blobs. I tried various different settings in my network analyst window and it keeps happening. I am using the latest StreetMap Premium network dataset.

Any help would be greatly appreciated.
