Hi all,

I’m trying to annotate variable rocks.  
I set 7 classes. When I find the incorrect labeling, I easily change the another class name using “annotation editor”.

For example, If I want change a class "chert " (yellow boundary) with “clastic” (blue boundary), I can easily change by clicking "save (Enter) button in “Annotation Editor” as follow

However, although I click class no. 2 (Clastic) and click “Save (Enter)” button, Nothing happens… I mean the class no. 1 (Chert) does not change to class no. 2 (Clastic).

Does anyone have an experience and idea for this issue?

Thanks,  
Jaeyoon
