Hi MITR Learning!
Sorry to hear you've run into this setback!
Can you share which keys were used when navigating through the slide? When proceeding through a course, the Tab key is used to move to interactive elements, and the up and down arrow keys are for moving line by line or item by item.
Also, it would be helpful to see the .story file you've been working with, as well as a screen recording demonstrating how you were navigating through the interaction. Feel free to upload those items here in the discussion or privately through a support case.
