Wordpress contact form 7 issue on elementor

Description

Need someone to fix my contact form 7 issue urgently within couple of hours
The issue is when i submit the form , it says that there is an error. But when I click submit again without changing anything, the form gets submitted and works well. I want someone to fix it
problem 2 : if we leave any required field empty we want the form to take the user to that part instead of just staying at the botthom.
