NULL Values in Speed Field

Hi,

I am finding that the QNEAT3 OD Matrix from Layers (m:n) is struggling when running in Fastest Path mode. I have a links layer which has a max speed attribute which is either populated with an integer or NULL.
In Shortest Path mode the algorithm can route between all ODs. However in Fastest Path mode it is only able to find ODs between nodes which enter/exit from links with speed data.

Does the algorithm use the Default Speed parameter when the speed attribute has NULL values?
