Hi Dave,

I seem to be having a similar issue with my model run. My 4 predictor variables are in the same projection (4269) along with AOI vector (4269).

Any recommendations? Is it possible that my predictor table ‘type’ columns are not correct (should be line\_intersect\_length vs. polygon\_area\_coverage)?
