Yes of course, there are so many "errors" that it seems to be unformatted. Looking to the scatter plot ("View/Scatter Window" from the GUIs menu) shows that the second side in fact is very well formatted! Its just the wrong format (opposite direction) and therefore not in the pattern you choosed to decode...
To make a preselection for your floppies, you may also view at the write protection. Flippy disk should have two notches, one for each side. Real double sided disks(like 1571 format) do need only one notch for writing on both sides.
