Syncing develop settings resets them to defaults

Sometimes when i select multiple edited photos and make some adjustments (just moving the toggles of the 'main' photo or syncing with cmd-shift-s) - some photos become flat, with all the settings reseted to default. I found that when i change selection to  some other photos, and then return to the corrupted - it becomes 'edited' again in some cases, and in some cases it loses my develop setting without a trace. This 'reload' doesnt work often. This problem also was on win laptop, and it freaks me out.
