When I make a event with dates 10 april to 15 april you can select weekdays or you can make extra dates.
When I open the list you see 10 april to 15 april and for example an extra date. When I click on one of the date items, for example 14 april, it opens an new page with information. But the information by date is still 10 april. But that must be 14 april because I clicked on 14 april.

I use the last version iCagenda_PRO_3.5.2 I buy yesterday.
