Chapter 1: The Mandalorian - S1-E1
Audio problem: Mando's prisoner says that the Livery Cruiser "won't come out of your end", but the line is dubbed over, the actor just opens his mouth when he's being hauled off the speeder. (00:05:25)
Chapter 5: The Gunslinger - S1-E5
Audio problem: Amy Sedaris hands the rifle to one of the droids as she walks closer to the baby. The droid puts the gun down and a sound is played as if he set it on something solid, but in the next shot the rifle is gone and there's nothing but sand around there. (00:06:50)
Chosen answer: They could be just like wrinkles from age, like the elderly Togruta in the Zygerrian slaver arc in The Clone Wars series, as Ahsoka is considerably older than her animated appearances. I think there is probably a character design/stylisation aspect to it as well - the other Togruta we've seen in live action, Shaak Ti, has four segments or folds in her lekku that were not visible in her Clone Wars appearances, so it would seem the character design in Clone Wars and Rebels reduces such features.
