Sometimes, the Wiki differentiates items with identical names, then the in-game names get changed and the Wiki doesn't get updated to match. It is possible to edit the text shown for a link, but I don't know if it's possible to edit a page's URL once it's created, so you get legacy things like that.
In the Flash version, a lot of items used an abbreviation on buttons, which were copied into Shop pages and the like. The JavaScript has more room for proper item names.
We also lost a lot of editors during the conversion process and most of them haven't come back. It's much harder to read the JavaScript code and the developers stopped updating the GitHub back in the Flash days (and recently had to delete it entirely).
