Duplicate post issue when scrolling in Casper theme

[dasom]

1. Duplicate posts are visible when scrolling and loading a second time.

//main: index.hbs
//sub: tag.hbs

2. When a subpage is loaded, a post that does not match the tag of that page is displayed.
   (ex. If it is a knowledge page and you see customer cases)

scroll loading or infinite scroll issue…?? I don’t know…
