I got my 1040 and synced three profiles from my 1030 with GC iOS. In the data screen editor everything looked good. All the screen are the same as they were on the 1030. However, when I started a ride the first screen was blank in all three profiles. Not missing or an extra screen since the right number of screens were present. Just that the first screen in the list displayed as blank.
This is how it looked in the editor:
So, I recreated the screen and deleted the original and everything was fine. It seems that there is some sort of glitch in the profile transfer.
