Can't stop Lightroom from applying synchronize setting

[MarkDB]

Whenever I enter Lightroom, and begin working with images in either a collection or in a folder, after a few minutes, Lightroom starts applying a crop to all the pictures in my current filmstrip.  I can't find where to turn this off! If I go into Develop and select the film strip images, and verify that the switch for the auto sync button is in the off position. I've restored all the presets from the preferences/general tab to their default values, made sure that the Lightroom Mobile synch is paused, and have gone to the sync button in the bottom of the Develop panel as soon as I enter a folder or collection, set all sync attributes to unchecked, but still find that Lightroom goes through my images, applying a synchronized attribute of a crop - always the same size (about 20% of the image) crop, usually in the same location on the image (center).  In Develop, the history shows "synchronize setting" but I do not understand what it is syncing with and how to stop that action.

Help!!!

I am a newer, beginning Lightroom user. This is driving me to tears!  I would be grateful for any suggestions that might work.

Hi MarkDB,

Please back up your Lightroom catalog from Edit>Catalog settings>Backup(when Lightroom next exits) and restore Lightroom preferences following this article How to set Lightroom preferences

Let us know if that helps.

Thanks,

AK

Wow, this worked! Thanks so much!

Is there a way that I could bulk remove the "Synchronize Settings" that was applied to my images? Right now, I am stepping back  to the previous action in my history list image by image as I work an image, but I have hundreds of images that have been affected by the "Synchronize Settings" that inadvertently was created in my presets/preferences.

Greatly appreciate your helpful advice!

O no!  The problem came back? Is there any evidence in the com.adobe.Lightroom6.plist  file to see what I am doing wrong? Is there a way to post the file if there is?  It went away by deleting the file, but I really, really, don't want this come back again.

Let me know if it comes back again. We might need system info from Lightroom.

Thanks,

In the bottom right corner of Develop are two buttons. What do they say? Is one of them showing AutoSync?

[MarkDB]

No, I the buttons are Previous and Reset. In Library, I see 2 buttons "Sync Metadata and Sync Settings"  but they are grayed out.
