Problem with Contact Form fields – all fields are mandatory

I’m trying out Quiz And Survey Master plugin and I’ve created my first Simple Form.

Under Contact Tab in settings I’ve set up that only a few are Required – see image of settings https://varnastarost.si/Support-temp/Form-COntact-settings.png

but when users are still forced to fill out all the contact details.
Are there any other setting that override these ones?

Site is running:
plugin version – Version 8.0.4
WP version – 5.7.7
theme – Newspaper 9.8
