Can’t display thumbnail when scrolling

[Ryan-the-hito]

I’m on M1 mbp and system is the latest Ventura. I found Telik will automatically show the thumbnail for the first 5-6 ones, but when you have more updates than that, it will stop to show the picture.

only the top are shown

Like above, if you update all, it will show some, but not for the rest when you scroll. I have also checked if it is because of my Internet, but it turns out to be no.
