What's wrong?

How can we reproduce the problem?

What's your environment?

Operating system: MacOS: Ventura 13.2.1
Orange version: 3.34.1
How you installed Orange: download from website

Works as intended. Why would you expect them to change?

The confusion matrix can be confusing. We thought that when you selected the target = 0 it became 1 so the confusion matrix would change. I tried to pose a similar scenario in ChatGPT and here is their explanation in two screenshots
