"Visit duation greater than" is not be counted

Hello guys!

I try to track the goal “visit duration greater than 0. minutes” but Matomo does not track anything. my first idea was, it has to do with this case How do I improve accuracy of "Time spent on page" and "Visit duration" metrics? FAQ - Analytics Platform - Matomo / JavaScript Tracking Client: Integrate - Matomo Analytics (formerly Piwik Analytics) - Developer Docs - v3 . But after a short discussion with the admin, it is not.

So, is there any mistake on me side? I am new in the Matomo world, but already learning/studying it, and I hope you can give me enlightenment.

Thanks
Debbi
