All font styles are not available on MS Word

Hello guys.

I’m facing an issue. I’ve installed Spartan MB. It has 7 styles and I’ve installed all of them. All the styles are working fine on Adobe Illustrator. But when I open MS Word, I don’t see them all except the bold one. Do you guys know how can I get all the styles on MS Word? I’d really help. I’m using Windows OS by the way.

Best regards
