Carousel Size too large

[Bastion]

Hi,

I can't solve a basic problem:
on my page the slides in the carousel are always shown too large, the lower part of the image is always cut. So, I have to scroll up to see the full image, which can't be the idea, p.eg. https://archphot.com/rappaport/
It seems to me as if Carousel always zooms in maximally but a little bit too far, 110% instead of 100%.
I tried everything. Gridder, Gridder Defaults, Carousel side 100vh or smaller ...
Whatever I do, the result is the same.
What to do? I simply want to see the full image incl. the white frame below.

Best
Peter
