VC2002: Element isn't a block
The element's name has a hyphen like a block's, but there's no block (or template) by that name, so it renders as a plain, unknown element and its parameters and slots are ignored.
How to fix
Check the spelling (the quick fix offers the closest block name), or create the block. Custom elements that a script defines are fine to keep: this is a warning, not an error.
Example
<hero-baner> - did you mean <hero-banner>?
