Thank you. I had looked at that inventory, but the title was confusing to me. If it had said something like: Final punctuation allowed at different markers. I would probably have understood. Anyway, I have now marked all of them as valid and I only get real errors flagged. The ie marker has no content and therefore no punctuation, so I assume it refers to the punctuation preceding this marker. Maybe by setting all as valid, I might not get an actual error flagged. I cannot see which ones might not be valid.
