You got to love these human editors.
Some of these directories just don't like articles in parts. Seems some spammers have been using these too much.
And they love this Title Case scene - even though this is becoming less and less used.
Like any human editor (and gawd, I've had enough in colleges and corporate scenes), they enter their own opinion into the scene - giving some technical detail as the supporting reason.
But I'm working through this all.
While I won't submit "part 1, part 2, etc.", I'll continue to excerpt from the books I've published. Just means original titles for each one and subtly changing the summary text. I still have the same amount of data to submit.
