Perhaps you aren’t familiar with the idea of episodic television? All episodes of TOS/TNG are episodic. This means that with very specific exceptions that are related to the over araching story, if there is one, nothing ever happens during the episode that will affect future episodes. It is literally the design of Star Trek from the begin. It’s why the episodes open with a nonsense star date.

TOS had nonsense stardates. TNG actually had a loose formula based on the season and episode number.
