However, in the dub, Tobi 'was taken to a different facility' and Misty is trying to 'find him', but she doesn't have any specific reason for hating Akiza specifically from the rest of the Arcadia Movement.

In the original version, Misty harbors an intense hatred towards Aki because the latter was allegedly responsible for the death of Misty's brother Tobi.

Even though Jack and Yusei have a rough history with each other regarding Yusei's Stardust Dragon and his previous D-Wheel, Jack was never really shown to have any intention to have Yusei thrown into the facility. In the dub, Jack Atlas was the one who set up the chip for Rally to obtain for seemingly no good reason other than to give more depth to Yusei's grudge with Jack.

In the first episode, Rally stole a chip for Yusei's D-Wheel, causing Security to hunt them down which then led to Yusei's duel against Ushio/Trudge.

Instead, Rudger Goodwin was originally the fifth Signer until he cut off his arm and became the Dark Signer leader, and Rex took Rudger's arm and replaced his artificial arm with it, in effect making him both a Signer and a Dark Signer, which the dub did not bring up at all.

Rex Goodwin was claimed to be the fifth Signer, even before his identity had been revealed, while it wasn't originally.

A large amount of story rewrites that cause plot holes and directly contradict characterization.
