- In this dub, Alice is explicitly said to be British, accent and all.
- Like with Smile, there are episodes left undubbed, though fewer this time around due to Doki Doki being a more plot-focused season. So far, the undubbed episodes are 9, 26, 29, and 34 to 38.
- In the original episode 16, Regina approaches the Cures to become friends with only Mana, while in the dub version (episode 15), Regina approaches the Cures with the intent of finding out the source of their powers, in order to become just as powerful as them and make her father proud -- she just becomes closer to Cory due to Cory being the only one who didn't have second thoughts about helping her.
- In the dub, episode 21 (22 in the original) ends with Cory screaming for the brainwashed Regina to stop with her behavior, and the scene of Cure Ace's appearance is transplanted to the beginning of the following episode instead.
- The scene of Regina's reawakening at the end of episode 38 is transplanted to the beginning of dub episode 31.
- In episodes 35 and 38 (43 and 46 in the original), the scene of baby Aguri magically growing into her current age in Mari's arms is cut, as to give the impression that Cynthia grew up normally like Regina did.
- A good chunk of the finale is cut (namely the entirety of Pell's screentime as Proto-Jikochuu (Parthenon Mode included), the aftermath with the spirit of Marie-Ange talking to the girls, and the reveal of Trump Kingdom as a republic), giving the impression that, once Lucifer was purified, the battle truly ended, and that Marie-Ange somehow came back to life. In addition to this, another scene is added to the epilogue: the scenes of Mana's wedding from the movie, meticulously edited to show Marie-Ange and Joe as the newlyweds instead.
