I need to remove a frame behind a QR Code which shows as a Fill.  Looks white on screen, but Fill square is Black.  It will select, delete, but I need to do over 300 files so would like a script to do this.  The Batch Processing using Actions in Illustrator doesn't work I get an error: The object "clear" is not currently available.

If I highlight the frame I wish to remove, the action works but as I need to do lots of files, I don't want to have to do this.
