Text-to-speech editor showing wrong text

This has only been happening today, and I've only opened one project, so I don't know if this is a weird glitch...

I have text to speech set up on all my slides on this Storyline 360 project. However, when I go to edit the existing text to speech, the editing window is showing text from different slides. If I preview the slide or the audio, it reads the correct text, so I know the correct text is there, but I can't get to it to edit it.

Example: slide 1 says, "step 1, first..."

Slide 2 says, "step 2, next..."

But if I click the Text-to-Speech button on slide 1, the editing window shows, "step 2, next..."

I have tried updating Storyline, restarting my computer, and closing and reopening the project several times, but nothing has helped. Does anyone have any ideas to help me avoid having to redo all the text-to-speech on every slide to get it to display correctly?
