some minor bugs....?

Hi Captains,after nearly 1000 hours flying MD-11, i sense there are still some minor bugs on this heavy:1.)imagine the pilot forgets pulling baro bug, after crossing TA or during climb and climbs with e.g. QNH 1018 to his final level, in this case FL330. If he notice his failure on his cruise level and pulls the baro-bug to QNH standard the machine doesn't levels FL 330 automatically, and it is nearly "frozen" on current hight!
