I am unable to add additional blocks outside of the automatically inserted Toolset View block when creating a new archive template. Any attempt to add a block results in it being overwritten and disappearing, limiting my ability to style the page or include extra content.
Solution:
The Toolset WordPress Archive block must remain the top-level block, but additional blocks can be added inside the WordPress Archive Output section. Alternatively, instead of using the default WordPress Archive, create a new page and add a View block that pulls data from the desired post type, allowing greater flexibility in page design and layout.
