If you go to the storage location (listed in MobileSheetsPro under Settings->Storage->Set MobileSheets Storage Location) and look at the stamps folder, it should contain the custom stamp on the Android device. Can you please check to make sure the file exists on the Android device that is showing the red exclamation mark? Also, what storage location are you currently using on that device?
