Image Resize in Gallery Page

Hello, my URL is https://www.corsewerks.com, the issue I have is on the Gallery page, if you look at the images on top, they are all displaying correctly but if you scroll all the way to the last two images, they are displaying very large thumbnails instead of the same size as all other images. The plugin used on this page is Simple Lightbox Gallery. I double checked all the images and they are all the same size as the ones on top. I can’t figure out why only these two would be displaying differently. I have been looking in the code, in lightbox gallery options for past 4 hours but can’t seem to find where the issue is. Appreciate any help I can get.
