Problem with Blog (Slider)

Hi,

I have the following problem:

I've created a new blog with about 100 articles sorted by year and categorized.

Due to the size of the blog, I'm using the slider with categories and sorting options.

Selecting the categories works fine, but after selecting them about 3-4 times, this happens (see video).

It happens when I select the categories from top to bottom and then select one above it again...

Note: Please urgently update the image selection problem. It's impossible to select an image when the selection screen immediately jumps back to the top. However, there are already several forum posts about this.
