There could be two possible reasons for this:
 * 1) There is a bit of a delay when you first launch the developer tools and when Chrome basically loads up extensions which displays an extra entry under the developer tools section. The minor delay is around 10 seconds tops. If "KanColle" tab does not appear within developer tools, try closing the developer tools tab and open it again.
 * 2) The selected option from KC3 Kai its own respective drop down menu that you chose may not have "KanColle" tab available from within developer tools. I am unsure of the third option but from developer's version of KC3 Kai there are three options, two of them I have tested and verified that they have a "KanColle" tab within developer tools:
 * Play via API link (tested myself - though I personally no longer use).
 * Play on DMM website (untested)
 * Play via DMM (i)frame (tested myself - known as "MenuPlayDMMFName").

It also appears that you have tried to load KC3 Kai panel when you're already in the game. I would personally advise against this because this may cause undesired effects. The ideal time to load KC3 Kai panel is when you chose the two former options I have listed above and have tested before you enter into the actual game itself. By "actual game" I meant at the Game start screen where you see a big button towards the bottom right of the page and below the button is the name of the server that you belong to.
