itinerary sequence dates

I am having problems sequencing the tour daily itinerary events. Okay day 1,2,3,4 then it jumps to day 6 and then back to day 5 7,8,9,10,11,12 and day 13.

Tried editing the sequence – looks okay when it’s in Event mode but when I go to the published page it back to the wrong sequence. What can I do?
