Multiple custom fonts not working

**Describe the bug**
I am following the documentation to register two fonts, but only the one can be utilized.

Here is the code:

`Font.register({
family: 'TeleNeoWeb-Regular',
src: '/assets/fonts/TeleNeoWeb-Regular-font.woff',
})
Font.register({
family: 'TeleNeoWeb-Bold',
src: '/assets/fonts/TeleNeoWeb-Bold-font.woff',
})

const globalStyles = StyleSheet.create({
h1: {
fontFamily: 'TeleNeoWeb-Regular',
},
h2: {
fontFamily: 'TeleNeoWeb-Bold',
}
})
`

The Regular font is shown on both h1 and h2. It seems that multiple custom fonts can not be rendered.
