Xcode: customize font display wrong style in Xcode storyboard

Question

I added some customize font into my project and want to use it in the storyboard.

The font names are:

Frutiger 45 Light.ttf
Frutiger 55 Roman Bold.ttf
Frutiger 55 Roman.ttf 

Then I want to use it in storyborad by selecting an UILabel and set the font.

As you can see in the images, the name Family is Frutiger, but the Style is all Regular.

Is the font file name problem? Tried "Frutiger_55_Roman.ttf" and "Frutiger-55-Roman.ttf" way, not working so far.

Thanks!
