Dear Parinda,
You could provide your wp-admin (URL, Username & Password) access using our Envato Market (themeforest) profile contact form https://themeforest.net/user/themelooks#contact (screenshot as reference http://prntscr.com/gkmr2r ) including this support topic link as a reference to review the issue to fix.
However, before we check your website we need to know, did you installed any 3rd party plugin or update/changed anything on your website before raised the issue?
Why the pricing table filter suddenly got vanished?
Best Regards,
ThemeLooks Support Team
