Hello, @Manish Gupta,
In order to solve your issue simply go to the Dashboard >> XStore >> Theme Settings >> Theme Custom CSS >> Global and paste the below code at the bottom of the CSS box there.
body:not(.logged-in) div.etheme-price-filter {
display: none !important;
}
Then save settings and check back to your site after clearing the browser cache.
