Hello,
I have visited your website.
I have inspected your website. The issue is you are using the WoodMart logo and the mobile background image that is coming from our demo site.
Please replace or delete the images this will fix the issue of the padlock.

You can inspect the website to check the images.
For the header icons it seems that you are not changing the correct header. Please edit the homepage and check which header is used as the custom header for the page then try editing the header.
