Gekiretsu shoujo Shanpû toujou! Watashi inochi azukemasu - S1-E15
Other mistake: After beating up the dummy, Akane is thinking back about her 'relationship' with Ranma. During her thoughts, the first memory that pops to her mind is something that has not happened yet, Ranma moving in front of her and saying "She's MY fiancee", part of the story arc at the ice rink that will happen only later in the series (Episode 20 of the English dub, which unites both Ranma series in one, episode 8 of the Ranma Ranma ½; Nettô-hen series; "Kikiippatsu! Shiryō no Bonodori"). More recent home video editions have fixed the mistake, airing the ice rink episodes before the Shampoo ones - which is where they should have been in the first place; Shampoo's debut episode was preempted last minute in the original airing to help unsatisfying ratings with the appearance of one of the most popular manga characters.

Other mistake: The episode opens with Ranma eating an ice cream with Akane. He (in female form) acts as he never had one before and Akane says "Don't tell me you've never had ice cream before!", and that's the case, apparently. But, episode 11 opened exactly with Ranma charming a shop owner into handing "her" a cone, commenting that "when it comes to eating out, being a girl is the only way to go." (00:02:00)

Other mistake: Ranma chased by Shampoo at the end of the episode jumps down from the roof. He leaps at a distance from the wall, and he is supposedly in a rush to escape the pursuit, but Nabiki is able to pour from the kettle on his head when he is close to the wall and not in a rush to move away from that spot.
