Running SDR Model - Stream Gura raster not populating stream network

Hi all, I am currently enrolled in the Introduction to the Natural Capital Project Approach course, trying to run the SDR model using the Gura sample data.

My first question is what should I put for the Maximum L Value, which is required for the model to run. The instructions on the course does not include this parameter. (I put 122 after reading another post, but I wanted to know if there was a specific max. for this model).

My model successfully ran but I noticed that my stream raster does not look like the example in the course.

Please let me know if you’ve had a similar issue and how you fixed it, thanks!
