Network Analyst results extending beyond the cutoff limit?

I am working in Network Analyst to generate 1/2 mile walkshed buffers around specific origin points. The network includes a roads layer and a sidewalk layer. I set a cutoff limit of 2440 feet, however when I run the analysis, the results are extending out beyond 1/2 mile.


1/2 mile euclidean buffers are shown in red, and network analyst results are shown in orange. The orange points are the origin facilities from which the network is traveling away from. Does anyone know why the results are extending beyond the 1/2 mile buffer?


The corresponding results table is shown below and indicates that the maximum cumulative distance is 2440 feet, however this is not reflected in the results. All data is projected correctly and shape length fields appear to be calculating length correctly.
