Typos are the job of proofreaders, not editors. It's the last step in the process.

There are several kinds of editors. The kind of editor that catches the issues you're talking about is a developmental editor I believe. They make sure the story is hanging together. If you're really interested, here is an article about all the different people involved in the editing/proofing process. https://www.gcu.edu/blog/language-communication/types-editors

Probably if you're not working with one of the big houses, your book isn't getting the full treatment. And if you're an indie, you're paying out of pocket. I proofed a book for a gal whose book needed 3 levels of editing it didn't get. Plus fact checking. She used quotes that weren't real or were paraphrased. I flagged those for her (she wasn't paying me for that). When she sent me a copy of the book, she hadn't fixed them.
