Tablet caption text doesn't update when changed on desktop view?

I searched the forum, and I can't find anything on this.

I'm using break point mode for responsive design (as these files were developed a couple years ago, and we've got hundreds of slides) and many times when I edit the text on the desktop view, the tablet portrait view does not update. Other times when I edit the text in the desktop view, the tablet portrait view updates. I've just lived with this fact for a while, and edited the text manually in both places when it pops up. But I'm wondering if this is a bug? Or if there is a fix? It's pretty time consuming.

I'm using Captivate 2017, but with older responsive files that cannot be converted to fluid boxes or anything like that.

However the second part of this equation is, I've given the English Captivate files to a translation company, and they've translated the files into nine languages. They used the XML export feature to translate it, assuming that all text in the Captivate file would be in the XML file. However on the tablet portrait view in many places, the English still remains, but the desktop got translated fine. We've searched the XML file for English text that remains, but it's not in the XML. It's a little late to try the Word export since the translation is completed, and it also takes a hundred times longer then the XML export/import. The amount of time to manually fix 9 captivate files with a couple hundred slides would be unthinkable at this point. Anyone?
