Problem: When I either try to verify or restore the split image, I click on the first file of the split image, and the "File name" fills red with the [Next] button greyed out. However, if I highlight the second file of the split image, then I can click [Next] but it fails, as shown in second image below.
Temporary Fix: By changing the file-name without underscores the image will then allow me to verify and restore.
Again, the underscores do not affect our non-split images. I thought I'd post this in case anyone else is having the same problem.
