Hi ChenxueMa,

Thanks for reaching out and detailing what you're experiencing!

I created a sample microlearning with a text block connected to a statement block. I'm unable to replicate the behavior you describe. I'm testing this in Chrome Version 131.0.6778.205. 

• Can you please check that your browser is up to date, or try a different browser?
• Have you tried publishing the microlearning again to see if that makes a difference?
• If you publish for web distribution, does the issue still appear?

If you're willing to share a copy of your file with our team, we'd be happy to take a closer look! We'll delete everything from our systems once troubleshooting is complete.
