Thank you for your reply and suggestions.
It was a reused slide from another presentation. But they all were, and only this particular slide is having the issue. And as far as I know, the original was created in English.
When I right-click on the underlined words, Spanish alternatives do come up, so I've been searching for anywhere and everywhere that may have Spanish selected....but I've found nothing amiss.
I did insert a new slide and recreate, but the exact same issue came back. So strange!
I think I will just have to move on for now, and start completely from scratch on the next one.
Very strange, nonetheless.
