It's a known issue. The Text is drawn but in the wrong place. It's not
classed as a bug as Visual styles only supports Top Aligned Tabs.
Either draw the tabs yourself (you'll either lose Visual Styles or have a
fair amount of work restoring them) or use a third party TabControl instead.
See some of the tips on my site for the basics of ownerdrawing the
tabcontrol.

TabControlEx and TabControl 2 are free to use in any way you wish and they
both overcome this issue as well as several others.

If you only want to overcome this issue, then I would suggest that you use
TabControl 2, but TabControlEx has some other frequently requested features
which you may or may not like.
