CMS layout always stay vertically

Hi guys,

I don’t know if I clicked something wrong or something else. Suddenly the horizontal layout doesn’t work for CMS component.

I created a section and added a container, and then added a CMS collection list. It all worked well until I clicked the horizontal display button. The CMS list still stayed vertically, which is expected to be horizontally displayed in the container.

Can anyone help with it?
