Continuity mistake: When Wolverine first places the time band on his arm, it is on the upper half of his forearm, just above where his glove ends. When he is pulling the gun out of the cabinet, the band has now moved closer to his hand. (00:08:00)
Phaneron Other mistake: When the Lady Gardener touches the flower on her table, it instantly dies, which elicits a shocked reaction from her. This show establishes that mutant powers begin to manifest during puberty, and this character is middle-aged. A character that has been living with their powers for that long shouldn't be shocked at what her powers do. (00:03:56)
Phaneron Continuity mistake: When Apocalypse is ordering War and Archangel to attack the tanks, Archangel's decollete is the same light blue color as his skin, when it should be the darker shade of blue that his outfit his, since his outfit leaves his face and hands exposed. The photograph Xavier shows Rogue of Archangel later in the episode also depicts the same error. (00:09:30 - 00:11:12)

Phaneron Days of Future Past: Part 1 - S1-E11
Continuity mistake: When Bishop peeks out of the alley after arriving in the past, there is a wrecked car on the right side of the screen, with a fire hydrant near its front bumper, on an uninterrupted sidewalk. When the shot changes to Bishop stepping out of the alley, the fire hydrant is now by the car's rear bumper, and there is a driveway leading into the alley. Additionally, the building that is behind Bishop changes color from red to green. (00:10:09)

Phaneron Days of Future Past: Part 1 - S1-E11
Continuity mistake: When Bishop is telling Wolverine that Sentinels only want to kill rebellious mutants, his neck alternates between being the same color as his skin and the same light blue color as his uniform. (00:04:51)
Phaneron Days of Future Past: Part 1 - S1-E11
Continuity mistake: When Wolverine is asking Bishop if he knows him from somewhere, his pupils have been drawn as small black circles inside a blue circle that are the same color as his eyes.
