Here's a screen shot of what I mean:
This is just an example. You can see that in the Amirs Stables there are two units available for recruitment, but for some reason each unit is listed twice. I've checked other buildings such as barracks or archery ranges and they all have this bug. I have also tried loading a campaign with a different faction and this same bug persists.
I have just reinstalled BC and patched it to 2.02. Did something go wrong with the installation or is this in everyone's game?
