Lightroom sorting of images has changed unexpectedly?
A catalogue of 10,235 photos has changed the sort order. It is set to be sorted by file name (which was alphabetical) and has worked fine until today. Now, much in the catalogue is out of order thought it is still set for "file name" I've tried switching to a few others and then back but the problem remains. Since when does a name beginning with At come before As. It is also set for ascending. Would appreciate any help!
Thanks in advance-
