Validation errors not showing with ajax

Hello, i have a wierd problem. I’m usuing a form with required field and when send my form with ajax (default situation in contact forms) it shows general error in “wpcf7-response-output” but not show any span “wpcf7-not-valid-tip” with specific error in every required field. I see code and any of this fields have “aria-invalid=false” and would have to have “aria-invalid=true” . i think this is the issue why not showing errors, but i don’t know how solve it.

I need some quickly help, it’s urgent for me.

Thank you.
