Forum:Category Exhibition Thumbnails Issues / Questions

So I've got the Wiki Features "Category Exhibition" setting turned on for my wiki, where a category page displays all articles in that category rather than just a few. It works pretty nicely, but I'm having a few issues with the image thumbnails.

Usually, if I have an article which previously didn't have an image, and later an image is added to the article, it doesn't update immediately but takes a day or so, which I understand and which is normal. BUT on some pages, adding an image does not change the thumbnail. I've got images which have been added to pages two weeks ago which still show text thumbnails on the category page.

^ Here is an example of a category page. Some article don't have images yet and should be represented by text thumbs, but some should have the image thumb updated by now. Check out the article "Chameleon" - the image was added 15 days ago and it's still a text thumb. Do I have to make an edit on the Chameleon page or something for wikia to make this change?

Second issue is less important, kind of an annoyance. I notice smaller images are given an ugly white or black border/background when thumbnailed on a category page or in the Read More section. Any way to disable this? If not, can someone clue me in to the threshold for this? What dimensions does my image have to be to avoid this border?
