I am pretty sure I know what is wrong, but just out of curiosity, when was this screenshot taken? How long have you had this problem?

I am actually getting anywhere from 1 to 3, which is really odd. Anyways, I suspect the problem is this script which, as far as I can tell, is an older script that is supposed to do something similar. I would suggest no longer using this script since it also appears to have a few other issues (ex. doesn't generate proper link for VisualEditor). Although, I am not entirely sure since there is a lot to sort through and not a whole lot of comments to indicate intentions. Either way, this is the one that should probably be dropped. It is being imported via your MediaWiki:Common.js.

Why do I think it is this script? Well, I noticed that I never get multiple buttons using Internet Explorer. Internet Explorer is not compatible with VisualEditor so Wikia removes that edit option. Jgjake2's script checks for this edit option and exits if it isn't found. So what I think is going on is that TabViewEditLinks is working fine and adds an edit button. If you are using a browsers that can use VisualEditor (ex. Chrome and Firefox), Jgjake2's script also runs, detects the edit option, and adds a second edit button. If you are using something like Internet Explorer, Jgjake2's script doesn't detect the edit option (because it isn't there) and then exits without adding a button. Therefor only the button placed by TabViewEditLinks is there.
