ArcGIS Pro Model Builder Runs with No Result

[RyanMcCluskey1]

I'm using ArcGIS Pro 1.4.1 and transferring some arcpy scripts from Desktop to Pro. Odd issue with a simple script that applies symbology. It works when I run it in Model Builder but fails (although says it ran) if I run it as a tool in ArcPro.

Anyone have an issue where a Model Builder tool works in the model builder window but not when run as a tool in ArcPro.

Thanks,

Ryan
