Too many episodes of "The Faithful: Women of the Bible"

"The Faithful: Women of the Bible" is a miniseries with three two-hour episodes. It is listed on imdb as having six episodes and the cast information is incorrect for some episodes.

Minnie Driver, for example, is listed as being in one episode. This is true because it is a two-hour episode. However, if there are six episodes, she should be listed in two of them. The date of first broadcast for each episode suggests that each two-hour episode consists of two episodes, but that's not consistent with the cast lists.

Also, I submitted a plot synopsis for the two two-hour episodes I have seen. Neither one is ideal but at least they summarize briefly what happened. I left out some details I wasn't sure of. When I do this with movies I take notes to make sure I got all the details, but I didn't do this in these cases. The synopsis for episode 1 contains details of what may be episode 2, and I don't know where the dividing line is. Episode 4 has a synopsis that I contributed (though it appears to have a summary of episodes 3 and 4, not just 4), with some details missing that I wasn't sure of, but episode 3 does not. There is no brief plot description for either. And again, I don't know the dividing line.
