I recall in the 70’s whenever some show would have an episode with UFOs, that signaled the end of that show’s series soon after.

"The Munsters"

Season 1, Episode 18: "If a Martian Answers, Hang Up"

Herman contacts by radio a "Helosian" from "Outer Limits"

Continued till the end of Season 2

"My Three Sons"

Season 7, Episode 17: "You Saw a What?"

No one believes Ernie when he says that he saw a flying saucer.

Continued till the end of Season 12.

"Gilligan's Island"

Season 2, Episode 9: "Nyet, Nyet, Not Yet"

Two Soviet cosmonauts land on the island, way off course from their target.

Continued till the end of Season 3.

"The Wild, Wild West"

Season 2, Episode 6: "The Night of the Flying Pie Plate"

Series continued till the end of Season 4.

That's just a small selection, disproving your "impression."
