InDesign applies 'title case' on its own
I am editing text in an existing document. As I continue typing, InDesign CC 2017 sometimes decides to change the letter of the earlier just-typed words to a capital. This doesn't always happen, but once it starts it continues until I move somewhere else in the document. (It may or may not happen in the new location as well.) Paragraph style is set to Normal case.
How can I stop this from happening?!
