ArcGIS Pro Classification drops a class

MansfieldGIS — Mon, 22 Dec 2025 14:59:08 GMT

I'm trying to classify an image using the classification wizard in ArcGIS Pro 3.5.4. The imagery does not come from the Living Atlus. When I run the classification wizard it runs but when it gets the the preview classificed image it drops one of my classes. That class has 169 samples and growing. I have reached out to Tech support they could not help me. Does anyone ever run into this issue before?

Thanks,

BUG-000180734 for ArcGIS Pro

not quite sure from the question if this relates, since there is no elaboration as to what they are referring to in the bug report.

I am trying to do a land classification from imagery that my employee had flown. I'm using ArcGIS Pro 3.5.4. I followed the steps in the Classification Wizard I created Training Samples and Classification Schema. I created new Training Samples and Classification Schema several times (see Attached Training Samples). Followed the defaults in the Image Classification Wizard according to ESRI Tech Support. Ran the classifier it went through all of the steps. When it got to the Classified and Preview Classified list Knotweed had been dropped. ESRI Tech Support said it was a bug and marked as a bug. I've been working on this for a year on and off I really would like to see if I could get this working any insight would be great.
Thanks, Chris
