Having trouble converting an .epub file made in Sigil to .mobi format for Kindle.

Fonts are embedded and .epub version displays correctly through iBooks.

@font-face definitions from .epub css file as follows:

@font-face {
font-family: 'StarlingBook';
font-weight: normal;
font-style: normal;
src: url('../Fonts/Starling-Book.otf');

}

@font-face {
font-family: 'StarlingBold';
font-weight: normal;
font-style: normal;
src: url('../Fonts/Starling-Bold.otf');

}

@font-face {
font-family: 'StarlingBookItalic';
font-weight: normal;
font-style: normal;
src: url('../Fonts/Starling-BookItalic.otf');

}

@font-face {
font-family: 'StarlingBookSC';
font-weight: normal;
font-style: normal;
src: url('../Fonts/Starling-BookSC.otf');

}

@font-face {
font-family: 'StarlingBookItalicSC';
font-weight: normal;
font-style: normal;
src: url('../Fonts/Starling-BookItalicSC.otf');

}

@font-face {
font-family: 'UniversRoman';
font-weight: normal;
font-style: normal;
src: url('../Fonts/Univers-55_Roman.otf');

}

@font-face {
font-family: 'UniversItalic';
font-weight: normal;
font-style: normal;
src: url('../Fonts/Univers-55_Italic.ttf');

}

I've attached a couple of screen shots of the conversion panel in calibre. Embed referenced fonts is selected and they are all .ttf or .otf format so I'm not sure what is wrong. I've converted files like this before and not encountered this problem.

Can anyone help?

Thanks!
