Hi ​@_UED_UX5,

I understand you've set "Vertical" scroll behavior on a frame, and also you're seeing "Fixed" in the Layers panel above the contents.
 

You might already know but let me clarify a bit about the scroll behavior options:

• Vertical: This setting is for "Scroll overflow" and you can apply to top-level frames.
• Fixed: This setting is for "Scroll position" and you can apply to individual layers within a frame that has scroll overflow applied.(When you set an object to "Fixed," Figma places it above other layers in that frame and labels it "Fixed" in the Layers panel.)

So, in your screenshot, it looks like "Vertical" is applied to your top-level frame named "Mobile," and "Fixed" is applied to your "#内容" layer within it. You can check more details in this guide : Prototype scroll and overflow behavior

Could you please tell us in a bit more detail what behavior you're expecting and what the current problem is, after reviewing the document above? Also, if you can share a video recording demonstrating the behavior, it would be super helpful. 

This will increase the chances of our community experts being able to help, and it will also give us the necessary information to connect you with the appropriate team if needed.

Thanks,
