Yes, that's a well-known bug. It has been dealt with in a five-page thread with 44 posts and more than 1000 views in the "Bug report" forum, here:

But to speed things up, here's the workaround:
Go to podbot.cfg and change whatever setting you have for the "detailnames on/off" option. I.e., if you have detailed bot names (with "POD" tag and skill number) on, change it to off and vice versa. Save, start a new game, and the names will be back. Now you can change detailed names to your preferred setting again, and things should work.
Oh, and next time when you see a bug, take a look at the "Bug report" sub-forum to see if there's already a thread about it, ok? Btw, this thread doesn't belong into the general forum either...
