disappearing thumbnails & cropping issue

Hello!

I’m having a problem with one of our pages using the Meteor Slides plugin. New slides uploaded do not show up as thumbnails, and some of the existing images are cropped weirdly. It’s not happening on any other page, so it seems unlikely to be another plugin affecting it.

Here’s a link for reference:

I’d really appreciate it if someone could provide some insight!
