League of Legends (LoL) Question: Editing an already published guide

So, a couple days ago i published my first guide here on Mobafire, and since then i already came up with some ideas on how to improve on it.
The problem is, when i click on "Edit", do the changes and click "Save", the edited version doens't replace the old settings, but when i click on "Edit" again, it shows the updated version. Do i have to click on "Publish" for the new version to go online? (i'm pretty sure this is the situation but i'm not entirely sure)
