List loading is reset in the middle

Hello. I am having a little trouble with the loading of the listings, so I am asking for advice.

We are creating a list like a Twitter timeline where users post content and it appears.
The loading settings for this list are as follows

Loading occurs as you scroll, but it resets midway and returns to displaying only the first content that is loading.

Here is a video of it in action.
Suddenly the screen goes blank and only the first loaded content is displayed.

Does anyone know how to work around this?
