I have an AI task to check if what the user said is a country or not. If yes then the workflow continues, but if not then it goes to a node fallback to say something like "this is not a country, please input a country." And as you can see in the images I input "keyboard" and AI task detects it as a country, which is not what I want. Is this an error or is AI task not that advanced? Is there another way I can do this? As I think this is a really important feature.
