Renaming this thread as, even if there were an issue, it would in no way be a "Dell bug" !
Not seeing the basic specs of your selected Mac model under the "MacBook Pro" line (like size, year and TB ports) is likely to be linked to your bootloader settings. Do check them out. Nothing to do with laptop's BIOS for sure. Can't say more, you've not bothered to post any details of your Hackintosh setup whatsoever.
This being said, it's such a minor matter, I wouldn't waste much time on it...
