AI Text-to-Speech Generating Captions Even When Box Unchecked

Hello,

Has anyone else experienced Storyline generating CC with the AI text-to-speech tool even when the box is unchecked (screenshot attached)?  Storyline is adding them regardless of whether I check the box.  It takes the text as entered and uses those for the caption. I prefer them to not be generated this way because:

• I add punctuation, caps lock, and syntax to the text to manipulate voice emphasis, pauses, etc., that I don't want in the captions
• Generating captions via Manage Captions -> Generate with AI after the fact tends to group and space caption blocks more appropriately
• Not auto-captioning helps the review process, as the accessibility checker flags captionless bits

I couldn't find any other posts on this so I'm wondering if it's a universal bug or just my install.
