Glyph preview of PostScript fonts


I noticed that Corel Draw doesn't show a proper glyph preview of PostScript fonts. It only shows empty glyphs (see screenshot). Other than that this font seems to work fine. When I double click on an empty looking glyph, it will also insert the correct glyph. I just don't see what I'm clicking on.
I tried to install the font with Corel Font Manager, but even there I see the same thing in the glyph preview.
Is there a way of fixing this? I'd really need to see those glyphs.

Thanks in advance!
