P: Post processing disappearing from Export window when checking presets

Yes, it's fixed, now it works as expected, thank you!

Updates to Lightroom Classic, Camera Raw, and the Lightroom Ecosystem were released yesterday and contain a fix for this issue.  Please install the appropriate update and see if it solves this problem. You can read more about the updates here.

Thank you for your patience. 

Thanks for reporting this. We have logged a bug for this. 

This is an obvious bug. The Post-Processing panel should vanish when presets are checked! It should just be disabled like the other panels when multiple presets are checked. All panels should be enabled when no presets are checked. I also agree that if one preset is checked, then all panels should be enabled.

Sigh, it doesn't work in general for me either (Mac or Windows).  I was initially testing with a preset that had a missing post-processing plugin:



and with that preset, the Post-Processing section comes back after unchecking and clicking the name. But it doesn't happen in general with presets that don't have such errors.

Unchecking and clicking on the preset name doesn't make the hidden section reappear, at least for me (Win10).

A simpler workaround is to uncheck the preset and then click on its name (not the checkbox). 

This is a bad UI design -- please vote on this feature request to change it:

By closing again the dialogue of exportation then to open it again, this option is again active. proved on macOS. For me, this resembles a neglect if they abolish coaches every, it seems to me that option should be rekindled without having close again the dialogue of Exportation.

I'm not sure that that's the expected behavior (it is not from a customer point of view), after unchecking the preset.
The warning message says that "some sections are hidden when presets are checked". Which means that when I do uncheck the preset, the section should come back indeed the warning disappears, as I would expect.
Since the section doesn't come back, I assume it has been forgotten, while implementing the feature, to program the function that unhides the section..

Hi,

This is the expected behaviour when you select Preset. This behaviour changed after introducing multi-batch Export Feature. https://helpx.adobe.com/lightroom-classic/help/exporting-photos-basic-workflow.html#multi-batch-export. Same warning is shown at the below dialog and provided with a help link.
