Instagram Stories-Size in overview | iPhone 11 Pro | iOS 14

Hi, I have an iPhone 11 Pro with iOS 14 and since Saturday the Instagram Stories in the overview above are as big as on the screenshot. Not even 4 pieces fit in one row anymore. It should be like on the 2nd picture. Does anyone else have the problem?

What I have already tried:

- Reinstall Instagram

- Logged out and logged in

- Create a new account and see if it is the same there. It seems to be my account, with another account on my iPhone it is normal

I would be happy about help. Thanks!
