Hi @petewatterschatsworth,

Looking closely at your screenshot (template-part-header-trasformation-when-put-in-Template_3.jpg), I see exactly what’s happening.

To answer your question: A Header Pattern and a Template Part are not the same. A Pattern is a static blueprint, while a Template Part is a global reusable container.

The reason your Group and Row blocks “disappear” on the Template side (left column) is a visual behavior of the List View. When you wrap those blocks into the global Template Part “Kasa-Plata-Center-Header” (the purple icon), WordPress simplifies the tree view to look cleaner, hiding the internal wrapper blocks.

On your other site, you likely inserted the layout as a raw “Pattern” directly into the template without turning it into a Template Part, which is why the Group blocks remain visible there.

If you want both sites to look identical in the List View:

1. Open the Template editor.
2. Select the purple “Kasa-Plata-Center-Header” block.
3. Click the three dots in the toolbar and select “Detach Template Part”.

This will break it back down into regular blocks, and your Group/Row wrappers will reappear instantly!

Let me know if this helps.
