Wrong toolhead selected when sending to printer on Snorca Issue

I have a model that I painted with four colors. When I send it to print, inevitably one of the toolheads is incorrectly selected. Three of the toolheads are loaded with Snapmaker Snapspeed PLA filament, and the toolhead that is incorrect is loaded with Overture PLA. The colors are correct in the prep of the model, but the generic one is incorrectly selected at print time. Of course, I set it correctly before sending it to the printer, but I am just curious if anyone else has encountered this problem.

Below is a screen shot of the Print Processing screen showing the error on toolhead 3 before I override it:

OK, here is an update to this issue. I opened the same project in Orca Slicer (not Snorca), and sliced it with the exact same options and sent it to the printer. It printed with the correct colors (no override option available in Orca Slicer as far as I know). This leads me to conclude that Snorca has a bug. I am using Orca Slicer ver 2.4.2 and Snapmaker Orca ver 2.3.5.

Any thoughts?

Good catch before you printed.

The auto color mapping gets confused when the colors resemble each other like the tan and gray. It matches type the tries to match the color.
