Chapter 5: The Gunslinger - S1-E5
Character mistake: Mando's xenophobia against droids is so strong that he would not have them repair his ship (even harmless maintenance droids), nor take a cab with a droid driver, yet minutes later he talks to a droid bartender about a very sensitive topic like the search for illegal work.
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.
