@ theducks : #2 is what is in the original HTML file, before loading it into Sigil, and is correct if the original CSS file is in the same directory as the original HTML file. I would imagine that after loading it into Sigil, Sigil will have changed the CSS path to "../Styles/michael.css", to correspond with the new directory structure set up by Sigil.
@ michaelbr : I believe Sigil is creating those styles to replace formatting that has been applied within the HTML code rather than through the use of CSS (e.g. occasional use of <i> and <b> tags). The only way to stop this happening, as far as I know, is to ensure that all formatting is already handled via the CSS styles. However the styles created by Sigil are not replacing the existing styles in your CSS file, and don't prevent those from being used - they are simply in addition to those styles.
