Continuity mistake: When Mando repossesses the knob, the Child's ears go from straight to floppy in the space of a camera cut. (00:02:30)
Continuity mistake: The Client tosses the fob on the desk. He then fetches the pot of Beskar and puts it on the desk, but the fob changes position. (00:06:05)
Continuity mistake: The pile of beskar in front of the Armorer changes wildly in size and distribution depending on the camera angles. (00:09:15)
Continuity mistake: Mando knocks at the door and grabs the rude TT-8L/Y7 gatekeeper droid, ripping the eye part out entirely, nothing left on the arm. Mando then gets out of the Imperial hideout, he does it from the front door. By the door, but the security device has its eye back, still dangling off a cable. (00:19:55 - 00:24:30)
Continuity mistake: The scientist ducks into cover and the Mandalorian disappears, Batman-style. The position of Dr. Pershing's right hand is different in the last cut. (00:22:10)
Revealing mistake: During the whole escape from the bounty hunters scene, everyone is shooting at the protagonist, who is ducking into a baggage tug. Somehow the blaster shots from all those armed men do not make a hole, or even the smallest dent or burn mark onto the cart or its content of boxes and drums. (00:27:00)
Continuity mistake: Mando obliterates a guy on the roof using his long range rifle. He lowers the weapon, but he's seen lowering it again after the reaction shot on Carl Weathers. (00:27:50)
Plot hole: It is a well-known fact that Mando is the one who got the bounty for the target, and the bounty has already been cashed in. Fobs are, as shown, specific for just one target and bounty hunters return them. Yet everyone hanging around at the cantina has still theirs. And again, the bounty was already cashed in, and surely the imperial guy does not have another bucket of incredibly rare and precious metal to give away.
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.
