Other mistake: Supposedly the one difference between this universe and the movie canon is that Janet was infected by a zombie virus before she was saved by Hank and Scott. However, in the original movie Janet actively led them to her by 'possessing' Scott and while intelligent, these Marvel zombies can't communicate. Also, Vision is settled in Camp Leigh, which appears to be in perfect shape despite being hit by a missile powerful enough to penetrate in the bunker in Winter Soldier.
Suggested correction: As I said in my other correction, differences between the MCU movies and this show cannot count as mistakes, since they are showing us different universes with different outcomes. Just because Janet lead Scott to them in the movie doesn't mean that's what happened in the show's universe. Same with the "Winter Soldier" discrepancy.
Without Janet leading them, they wouldn't have even learned about her existence based on what was shown in Antman and The Wasp, and they show the laboratory scene pan out as it did in the movie. Althought technically she could have been infected by the zombie virus in the minutes it took them to get to her inside the Quantum Realm. You realise that it's flimsy and it relies on people essentially not remembering the movie, though.
Other mistake: Dialogue when the heroes locate the base; "The beacon's location was corrupted in transit, we have no idea where it came from." "Well, it looks to me your message is in non-linear hexacode" "That location looks familiar, Agent Carter?" And Sharon instantly identifies it. It may make sense when you write it, but not when there's no pause between sentences and no 'location' is shown. From "We have no idea where it comes from" to "Does it *look* familiar?" through a non-sequitur. (00:08:00)
