Other mistake: Grandma's Kisses: When SpongeBob is having his "mature conversation with Patrick," he tells him, "We are supposed to be adults!" In the next shot, when the camera moves over to Patrick, SpongeBob's right hand stays visible on screen; then it vanishes mid-shot. (00:06:46)

Other mistake: Grandma's Kisses: After Grandma pulls the plug from the floor, she kisses SpongeBob and says that he can kiss his Grandma and still be an adult.

Other mistake: SB-129: When Squidward goes inside the freezer and shuts the door, the freezer's door handle vanishes mid-shot. (00:03:09)
SB-129 / Karate Choppers - S1-E14

Continuity mistake: During the song, "The Very First Christmas," when Squidward is under the mistletoe hanging on SpongeBob's door frame, the door to SpongeBob's house is missing. (00:09:25)
Continuity mistake: After Squidward finishes giving away all his stuff, in the close-up of him as he says, "Am I insane?", not only is the yellow door knob on the left side instead of the right like in the last shot, but it also turns into a gray door handle. A shot later, it's back to a yellow door knob on the right side. (00:20:05)
Continuity mistake: The door to Squidward's house opens inward throughout the episode, but when Squidward comes out of his house on Christmas morning, the door opens outward. (00:13:49)
Continuity mistake: The doorknob on Squidward's house is either on the right or left side of the door throughout the episode, and it is even missing entirely in some shots. (00:11:30)
Other mistake: In the credits, Tom Kenny, Bill Fagerbakke, and Rodger Bumpass are credited for playing SpongeBob, Patrick, and Squidward. However, Patrick and Squidward's names should be "Patar" and "Squog," and "SpongeGar" should be shown along with SpongeBob's name (SpongeBob makes a small appearance near the start of the episode). (00:22:32)
Character mistake: Near the end of the second Patchy the Pirate segment, the narrator says, "What will SpongeBob do with fire?" However, the character's name is actually "SpongeGar." (00:14:29)

You Wish ('Shanghaied') / Gary Takes A Bath - S2-E11
Continuity mistake: Gary Take a Bath: The huge mud puddle around the tree was never there when SpongeBob first heard Gary's meows coming from the tree. In addition, when SpongeBob first looks down at Gary from the tree, the mud puddle is about the size of Gary, but in the next shot, it becomes tremendously bigger. (00:21:34 - 00:22:10)
Mermaid Man and Barnacle Boy III / Squirrel Jokes - S2-E4
Other mistake: Squirrel Jokes: When SpongeBob looks in the mirror backstage after finishing his second act, the holes on his face are not reversed in the reflection (one of the holes also vanishes and reappears mid-shot). The second time his reflection is shown, they are reversed. (00:20:18)
Chosen answer: You need to provide a little bit more information to be able to answer a question like this. In what region is it not being shown? I see it being replayed here in Australia fairly frequently. As for a general reason, there does not appear to be any for why it specifically might have been taken off the air in any country or region. Like any show certain episodes can sometimes not be replayed for long periods for unknown reasons.
