'Til Death Do Us Part: Part 1 - S2-E1
Continuity mistake: In the first shot of Rogue, Storm, Wolverine and Gambit watching Professor X's holographic message, Gambit's trenchcoat is colored yellow and his hair is colored black.

Continuity mistake: When Morph, disguised as Wolverine, bumps into Rogue, she is holding a steaming mug of coffee. When she tells him she is going to the rec room to take a nap, she is holding the mug sideways, with no steam coming from it. The camera was on her face for most of this sequence, so she couldn't have finished drinking it, and there is no spilled coffee on the floor, so the mug should still be steaming. (00:14:09)
'Til Death Do Us Part: Part 1 - S2-E1

Continuity mistake: When Rogue takes the unconscious Gambit into the War Room, she sets him down on the center table and stands at the edge of it. When she is showing Storm that she absorbed his powers, she reaches over to grab a coffee mug. There were no coffee mugs on the table when Rogue set him down, and they would be out of reach if they were located on another table. (00:16:57)

Revealing mistake: When Morph has sabotaged Beast's Danger Room session, the same shot of Beast running away from the projectile apparatus is used twice. (00:18:08)

Revealing mistake: After Morph laughs when the police have shot Storm out of the sky, there is a split-second flash of the establishing shot of the Veteran's Building Jubilee went to a little earlier in the episode. Note, this mistake may only occur on Disney+. (00:20:31)
'Til Death Do Us Part: Part 2 - S2-E2
Continuity mistake: When Morph parks the police car outside the gates of the X-Mansion, the front half of the car is in the immediate pathway of the gate. A couple of shots later, the entire car is parked along the curb. (00:02:50)
'Til Death Do Us Part: Part 2 - S2-E2

'Til Death Do Us Part: Part 2 - S2-E2
Character mistake: In the establishing shot of the movie theater where the Friends of Humanity meeting is taking place, the word "Humanity" on the marquee is incorrectly spelled as "Humanty." (00:06:32)
'Til Death Do Us Part: Part 2 - S2-E2
Continuity mistake: When Graydon Creed is giving his speech, the tail of the bird on the backdrop behind him is several feet above his head. When the shot changes, the tail is about level with his shoulders. (00:06:35)
'Til Death Do Us Part: Part 2 - S2-E2
Other mistake: The show establishes that Jubilee is Chinese-American, but after she accidentally blasts Wolverine, the way she pronounces "Sorry" is the way the word is typically pronounced by Canadians (most of the show's voice cast, including the actress who voiced Jubilee, are Canadian). (00:11:00)
Answer: Chris Potter, the original Gambit voice actor, did indeed quit the role in the 4th season. His last episode was The Phalanx Covenant Part 1 so it seems reasonable that Fox would limit the use of the character even though it was recast. It doesn't appear that Potter left the role due to animosity, he stated in an interview that he wished to play Gambit in the first live action X-Men film.
