scasey I have attached the InDesign file with the page that did not fully translate. It translated some of the text, but not all. I highlighted the untranslated text in pink.
Regarding this issue, I think the problem is that because this is the person's title, the DeepL engine (which is looking at the entire paragraph as a whole, perhaps) doesn't want to translate it because it thinks that the title is fixed (i.e. just like it wouldn't try to translate "Coca Cola" or something). But that's just a guess.
Anyway, I find that to get it to work, it is necessary to individually select each title individually, and then translate just that selected text, as in the screenshots below.
