I am currently working on a project using the InVEST Seasonal Water Yield model, and I have encountered an issue regarding the output rasters. While the **Quick Flow** output appears to be correct and matches expectations, the **Baseflow** and **Local Recharge** rasters are not displaying properly, as you can see in the attached screenshot.

Here are the parameter values I used in the model:

- **Alpha\_m** = 1/12
- **Beta\_i** = 1
- **Gamma** = 1
- **Threshold Flow Accumulation** = 1000

I have ensured that all input layers (DEM, LULC, precipitation, evapotranspiration, biophysical table, and watershed shapefile) were correctly formatted and projected. However, the issue still persists, particularly with the visual rendering and value distribution in the baseflow and local recharge outputs.

To assist in troubleshooting, I have attached all the input files along with a screenshot of the output for your reference. I would greatly appreciate it if you could kindly review the files and help identify the source of this problem.

Looking forward to your guidance.
