Can you post your stylesheet or the section that defines the h1, h2, h3 styles that Sigil supposedly changed?

Thanks Doitsu for your reply, sorry I forgot to include my CSS, here it is

/* Style Sheet for ePub Books */
/* Set margins at 2% (This gives a white border around the book) */

body {margin-left:2%;
    margin-right:2%;
    margin-top:2%;
    margin-bottom:2%;}

/* Text indent will make a paragraph indent, like putting a tab at the beginning of each new paragraph
The margin settings get rid of the white space between paragraphs, again so it looks more like a book
The text-align line justifies the margins. If you don't want them justified, change it to left, or remove
 that line. You don't have to specify a font, but you can */

p {text-indent: 1.0em;
    margin-left:0;
    margin-right:0;
    margin-top:0;
