Troubleshooting TypeError: __init__() got an unexpected keyword argument 'nonposx'

[janderson5417]

I have tried my own LAS as well as the example included in the data set, being careful to customize the XML curve names explicitly as they are found in the LAS file.

I get this error either way (and also have the issue in which depth is posted in reverse order as one would anticipate on a log!). Any insights or recommendations are much appreciated but...understand if you are no longer supporting this.
