Continuity mistake: In the scene where Apollo and Helo are boxing, Helo punches Apollo and this cause his head to bleed down his face. A few shots later the stream isn't as long.
Continuity mistake: When the box of explosive rounds is opened, the six rounds keep changing position. Sometimes they are nearly laid on a row, whilst in other shots they appear scattered randomly in the box.
Continuity mistake: Near the end of the 4th season episode "The Oath", Adama and Tigh choose to stay and fight rather than flee Galactica with Roslin. Apollo is not shown voicing any opposition to this. Yet in the next episode's opening, he is shown confronting his father, saying "No, Dad, you can't stay here". While this moment can be excused as having happened off-camera as the mutineers were shown approaching in the prior episode, it is the later show's narration which states "Previously on Battlestar Galactica" that is technically incorrect.

Continuity mistake: Lee Adama is a captain, and is addressed as captain, yet he wears the rank insignia of a major on his collar - three chevrons rather than two. This is obvious without pausing when he meets his father in the woods midway through the episode as there is a revealing closeup. (Note: timecode is from the Blu-Ray release). (00:22:30)
Answer: The original BSG has something of a complex version history. Several versions exist, but the rationale behind what you're referring to is as follows. BSG, before anything else, was a TV series - the 'pilot episode' was a three-part tale called "Saga of a Star World". In that three-parter, a last-minute alteration to the script meant that Baltar was ultimately spared execution, because Glen A. Larson, the series producer, decided that he liked the Baltar character enough to keep him around for the rest of the series. The theatrical version, which was edited down from the three-parter and was shown in some countries before the US TV broadcast, lost quite a number of scenes, including the one where Baltar is spared. The real continuity of the series can only be found in the TV version - the movies, all of which were created by editing together existing episodes, miss out scenes leading to such apparent continuity errors.
