No, it should say something like:
SS Fantasmagorica (Medium Tanker) 5872 tons. Cargo: Crude Oil. Crew: 48. Crew Lost: 17.
I can't show you a Commander log because I rewrite mine to tell the story of the attack, and relist all the sinkings together at the bottom, so it doesn't look the same.
[edit] Here is the last page from one of my patrol logs. You can see how I've written in my notes so it reads like a real log, with the sinkings collected at the bottom. I didn't change anything, just grouped them together. Also note that after you've saved your log it will show up in SH3 when you reload the game.
Check that you have Commander set to Auto Rollback. That may make a difference.
