Other mistake: Din tracks Grogu down through his chain code and other bounty hunters do the same throughout the series. As stated elsewhere, chain codes were implemented in the year 19 BBY AFTER the end of the Clone Wars and Order 66. We know that Grogu was spirited away from the Jedi Temple during the Slaughtering of the Younglings, so he was already a fugitive by the time they came about. No way they could stop and register him with the Empire while he was on the run from them.
Other mistake: The weaponsmith is smelting Beskar in a furnace in the first episode and the metal is liquid without any sort of incandescence. In the credits roll of episode 3, the artwork shows it red-hot, and in the season 2 finale we see it actually getting red-hot.
Answer: It's possible it's a different race of Jawas. The ones we saw before with red eyes were on Tatooine. These are a different group of Jawas on a different desert planet, thus probably have mutated or adapted different isolated from the other groups and have their own traits.
