Duel Identity, Part I - S1-E29
Other mistake: When Mai activates Rose Whip to raise Harpie Lady's attack points, the points are shown going from 2100 up to 2400. Harpie Lady had 1300 attack points and then gained 500 attack points from when Mai activated the spell card Cyber Shield earlier in the duel, so at this point, Harpie Lady should have had 1800 attack points, and then gone up to 2100. This is corrected to 2100 attack points every other time the points are displayed. (00:14:00)

Other mistake: When Yugi draws Summoned Skull from his deck, the spell card Rose Whip can be seen on the display of Mai's cards on the field in front of him. However, she doesn't activate this card until later in the episode. (00:08:45 - 00:14:00)
Duel Identity, Part I - S1-E29
Other mistake: When Yugi summons Summoned Skull, the defence points are displayed as 2300. Summoned Skull has 1200 defence points every other time it is shown. (00:09:07)
