What version of nopCommerce and the plugin?

Hi Maksim

We are using Nop4.40.4 and Plugin for 4.4 version 1.00

Well, it seems this plugin page (ShippingDetails) works incorrectly when HTML minification is enabled. We'll think about how to fix it.

As a temporary solution, you can disable minification (set EnableHtmlMinification setting to false).
Or if you have the source code, you can keep minification enabled and add this line (options.MinificationSettings.MinifyEmbeddedJsCode = false;) here, so that it looks like this:

.AddHtmlMinification(options =>
{
    options.CssMinifierFactory = new NUglifyCssMinifierFactory();
    options.JsMinifierFactory = new NUglifyJsMinifierFactory();
    options.MinificationSettings.MinifyEmbeddedJsCode = false;
})

Issue got resolved after disabling the  minification .
Thanks for your help Maksim , really appreciate it!
