How to Avoid AI Rejection

I don't think the history blocks are the reason. But can't say for sure. Because when I write in historical periods, I include a lot of small period details, but I don't devote many clustered paragraphs together filled with historical descriptions of events.

Since I started using Grammarly to catch typos and grammar problems, I always include a note that I have used it for those purposes. I can also honestly say I reject the majority of suggestions as they take the personality out of the story - perhaps it helps that I use British colloquialisms and shortcuts in phrasing.
On the historical stuff, maybe the old joke applies - to rely on one source is plagiarism, to use ten is research
