That means that MobileSheets is respecting the page order when doing the image correction, which is a good thing, but it is replacing the existing PDF when this occurs without a warning which is a bad thing. I will have to add a warning for that. What you need to do is have a song that uses the entire page range of the PDF (you can do this by copying one of the existing songs and changing the page order to "1-274" (replace 274 with whatever the last page is), and then applying image correction to that. That will process every page in the entire PDF, and since all the other songs share the same PDF, the image correction will work for all of them at once.

You can always create a library backup under Settings->Backup and Restore->Backup Library before experimenting with any features, and you can also use the swap file feature (or replace the file manually) if the shared PDF needs to be reverted for any reason.

Sorry for the lack of clear directions on my part.
