Google translation: "After automatically correcting the whole, it will be reset when synchronizing for each item. If you apply automatic correction to the whole and synchronize the settings for each item such as highlight, contrast, and saturation, the unchecked items will be reset to 0. Only 11.3.1 is in this state, and I was able to synchronize with 11.3 without any problems."
It's not clear exactly the steps you are taking -- can you please provide a precise step-by-step description of exactly what you're doing that doesn't work?
Google translation: "Automatically correct with multiple photos (around 400) selected in the library module, Then adjust the highlights, shadows and saturation in the Develop module and adjust them. Exposure, contrast, and exposure that should have been automatically corrected when synchronized with other photos at once The white and black level values will be 0."
Summary: Syncing develop settings to a large batch of photos can wipe out the previous settings of a batch Auto.
Details: Precise steps to reproduce on LR 11.3.1 / Mac OS 12.3.1:
1. In Library, select 1000 photos (a mix of raws and non-raws). (It occurs with fewer photos, but 1000 will ensure that you see the bug.)
2. Do Quick Develop > Reset All and wait for the progress bar to finish.
3. Do Quick Develop > Auto and wait for the progress bar to finish.
4. With all the photos still selected, take the first photo into Develop and set Exposure = -5.
5. Do Sync, selecting just Exposure, and wait for Sync to finish.
6. In the filmstrip, select one of the last photos. Observe that all the Basic sliders are 0 except for Exposure -- the Auto settings have been reset. Sample more of the photos in the middle of the selection and observe the same thing. As you get closer to the first photo, you may find photos that have the Auto settings and Exposure = -5.
This recipe also provokes the bug in LR 11.2 and 10.4, so the bug has been around for awhile.
Workaround: Define a preset with just Sharpening selected (e.g. your default sharpening settings). After step 3, apply the preset to the selected photos with Quick Develop > Saved Preset > preset, and wait for the progress bar to finish before proceeding.
A workaround that worked with past bugs with batch Auto, doing Library > Build Standard-Sized Previews after step 3, doesn't work here.
Historical note: A similar bug was reported in 2016. But in that incarnation, Auto wiped out later-applied settings. In this incarnation, later-applied settings wipes out the earlier Auto settings.
@Rikk Flohr: Photography, I've provided a precise recipe for reproducing this problem. Please move to Bugs.
