I noticed that too, and it's really annoying :/ It seems to be caused by the new infoboxes. Any images in them aren't counted as an image for some reason so even the thumbnail image in categories and the "read more" section show the next image on the page (or if it's the only one, then no image at all). You can see this very clearly in this category for example.

I'm going to report this as a bug to Wikia but since the infobox's are only in beta, it might not be fixed for a while. I also think they may know about this already but there's no harm in reporting it again.
