Hello @Code2018 

This is Amelia at PageFly - Shopify Advanced Page Builder app.

You can try the following steps I have provided to help you solve the problem you are facing:

Step 1: Online Stores > Themes > Edit code

Step 2: Choose file base.css or theme.css

Step 3: Add code

.shopify-section-header-sticky {
   margin-top: -30px;
}

Hoping my solution helps you solve your problem.

Best regards,

Thanks, Amelia, but that's not the best way to solve this problem, always adding new codes will decrease the speed of the site. 
If you need more to locate the key code, please tell me. I would like to add it.

@Code2018 ,

Please check the code of header file or theme.liquid file. Find the special character or text there that you shown in your screenshot.

I am sure there is some code typing mistake.

Add This css in your Edit Code > base.css File 

.section-header.shopify-section-group-header-group {
    grid-column: 1 / 1;
    grid-row: 3 / 4;
}
body {
    display: grid;
    grid-template-rows: auto auto auto 0px !important;
}
@media screen and (max-width:990px){
  body{
    grid-template-rows: auto auto auto 0px !important;
  }
  .section-header.shopify-section-group-header-group {
    grid-column: 1 / 1;
    grid-row: 3 / 3;
  }
}

Thanks, but as I said, add codes is not the best way to solve this problem.
