DeDRMd comic into azw3 and it's stretched

Hello, I successfully removed the drm from two leftover books I had on my Kindle app. One of them, I was able to convert from kfx to ebook without issues. The other one is a comic and was imported into Calibre as an AZW3 file for some reason, and the images are stretched to the point of being unreadable. Is there any known fix? Did I do something wrong while removing the drm?
