Version 4. I select all and the first one saves and then all the others are skipped. This looks like an old topic. Why hasn’t this been fixed?
@b609jk -Select All has is only to Export. If you want to do an action on the select all that is not to export, example, to add edits from the first file to the other files, you will need to right-click, then Apply, then choose in the options what you want to do.
