Hi,
Thank you for your kind words!
You can exclude pages from the results, this documenation will help. That color is more likely the results box background, you can change that here.
The issue with the checkbox is, that the font for it cannot be loaded. You have some sort of CDN actiaved on https://secureservercdn.net/166.62.107.20/f7a.3f7.myftpupload.com/ that hosts all your assets. The fonts are correctly there, but there is a CORS policy on your server or host that does not allow loading them, see console: https://i.imgur.com/U6xRY5k.png
Adjusting the policy or adding as exception will resolve the issue. You might have to ask the server administrator about that.
