1.0.5 NULL Values for "OD Matrix from Layers as Lines"

[jrbarnard01]

Hello @root676, hoping you could assist me with this. I am trying to use "OD Matrix from Layers as lines" tool to create a shapefile of the fastest optimal routes between each mexican capital. When I run the tool with red_vial (EPSG 6365 - shape file of road system across mexico) as the network layer and the points of each state capital as the start and destination locations, I get a result that has one or two lines displayed with the optimal route, but the rest is NULL. This has worked in the past with the same dataset, so it must be something weird. Could you help me with this? I am using 1.0.5 version of QNEAT but I don't see where I can adjust the tolerance (as mentioned in a previous thread). Here is what my results look like...
