Dehaze tool is missing

Any help ?

I took some pictures :

Dehaze is missing in Effect panel :

I am using Process version V4 :

...and french language is not a bug...

Thanks for your help

Edit:

I just realized that a lot of new features are missing, as if a old version of LR was running : guided upright tool, latest options on radial filter, etc. But I'm sure the software is up to date, and that what the "About" popup suggests.

The photos must be edited in the Process Version 3 or 4, earlier process versions will not show dehaze.

The Dehaze tool is in the Effects section. Is that where you are looking.

What exactly do you mean by "When LR is launched it disconnects from CC"?

Is this with new, recently imported, RAW images.

What Process are you using?
