Unwanted space under image

Hello, every new post I make on this site https://rememberingpersia.com/ using this block, for some reason there’s extra space between the bottom of the image and the pagination dots below it. Then after the auto play starts and after a few slides pass, the extra space disappears. The numbers of slides that have to pass before the space goes away differs on every post.

On this page https://rememberingpersia.com/miniature-dioramas-about-iran/dioramas-historical-sites-architecture-iran/tomb-of-saadi/ the extra space goes away after the 14th image loads. On this page https://rememberingpersia.com/miniature-dioramas-about-iran/dioramas-historical-sites-architecture-iran/house-of-strenght-zoorkhaneh/ the space goes away on the 10th image. Moving those images around does not solve the issue.

This does not happen on the old posts even though I’ve updated the block on those posts to v2 recently.

Any info you could give me on how to resolve this would be highly appreciated.
