I ran into this problem. (ie Dehaze missing). I tried all the usual, including logging out of CC, reboot my Windows PC ....etc.... The Adobe CC app told me I had the latest version of Lrcc. I created a support ticket with Adobe. In prep for a chat session I rebooted my PC, re-logged into CC (use the Help tab to find the Log In option on Windows) and then .... boom .... back in the latest version. Adobe chat could not explain what happened, even though they had remote access to my machine.
The sense I had was that I had launched the non CC version of Lightroom, even though I was using CC for as long as CC has been available.
My assumption ... a glitch with the Adobe sign-on server .....
Another suggestion ... if you are windows ... replace the Lr shortcut from the windows tool bar.
