When I open structure and access a question group. There I click add a question to the group. Sometimes the order (first column in question group-view) is not correct, but shows
a) to high numbers (12345, 12347)
b) numbers not unique (1 -> 2 -> 2)
c) numbers with steps in between (1 -> 3 -> 5 instead of 1 -> 2 -> 3).
