La classification ArcGIS Pro supprime une classe

Question

J'essaie de classifier une image en utilisant l'assistant de classification dans ArcGIS Pro 3.5.4.  L'imagerie ne provient pas du Living Atlus.  Lorsque je lance l'assistant de classification, il s'exécute mais lorsqu'il arrive à l'image classifiée en aperçu, il supprime une de mes classes.  Cette classe compte 169 échantillons et continue de croître.  J'ai contacté le support technique, ils n'ont pas pu m'aider.  Quelqu'un a-t-il déjà rencontré ce problème auparavant ?

Merci,

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
