...But I've always wondered why it called CC 2015, and not just CC...
They are still different versions regardless...
CC (14.0), was released in June 2013...
CC (14.2), Jan 2014...
CC 2014 (15) June 2014...
CC 2014.2.2 Dec 2014...
CC 2015 (16) June 2015...
CC 2015.1 (16.1) Nov 2015
ALL the above are 'CC' but each version is different from the last....hence its important to state which 'CC' version you use.
If you just state 'CC' then that's what I personally would expect you to be using.....the very first June 2013 release.
As we've proved here, stating just 'CC' threw me when trying to explain where things are....it was only from your screen shot and the fact that 'Save For Web (Legacy)...' was under the 'Export' menu that gave it away that you were in fact using 'CC 2015'.
Anyway......at least you got it sorted, and that's the main thing.
