Hi @Taren_Esri, 
Thank you for your anwser . I try it today. Even it save into feature class, some of the labeled samples was missing. I thought this is a bug when using the training sample manager to save the data. As it happened when the labeled samples over ~1470 for a single class.

For now, I try to do one raster with one set of data. And it work well.

Hi @Gary

A few things here. First, I would highly recommend storing your training samples as a feature class, and not a shapefile. The are overall more reliable, and provide more options for you to manage you data. Secondly, ensure you are accessing the same file that you saved when you reload the samples, as well as the same unmodified schema that you initially trained with. Mismatching the schema, or changing it after samples have been collected may cause data loss. You can find some notes on collecting training samples here.
