Why does Appstore not show 3 screenshots for my app?

I just deployed an app in the Appstore. When my app is in the list with other apps, they all show 3 screenshots but mine doesn't. Only when I click on my app it shows the 4 screenshots I uploaded in app store connect.

I have a presumption that it is because I entered 6.7" and 5.5" screenshots in app store connect instead of 6.5" and 5.5".

The problem is testing it: I have to deploy another version to try it out which is cumbersome. It would be nice to know beforehand whether such an amendment has a chance on success.

The app is called Your New Calendar and you find it when you search under "arjen" and scroll down some apps.

The screenshots will not be displayed in the App Store for the apps you have already installed. Uninstall your app and you will see the screenshots in the App Store for your app too.

I don't know why, but the Appstore now shows the 3 screenshots.
