Converted Entities not updating

Hi

I'm using 'Convert Entities' to copy an edge when adding an extrusion to a part. When I modify the original sketch, the 'converted' line is not modifying, instead it remains as the first part was originally drawn.

Am I missing something? Shouldn't the 'converted' line modify so that it matches the original line?

Thanks.
