Yeah, I've noticed that as well. It's a bit disappointing that the N900 won't display custom labels, as I find them immensely useful for some of my contacts who have a wide variety of phone numbers where I can reach them. It's inconsistent too -- for instance, it's smart enough to know what a FAX number is and label it "Unsupported" (which is a bit odd - it could just show "FAX" but refuse to dial - but still somewhat logical).. why won't it recognize a fully custom label? The fact that it then tries to override them on the Mac side though is quite maddening.
