This is expected - the AllDayArea will be shown only if the DateGroupDescription is on the last index in the GroupDescriptionCollection. As for the listed issues - can you please let me know if you are hitting one or some of them in the application? If so, you can share which ones, so we can try to suggest possible solution for the particular scenario. This one
is already fixed, however the status was not updated.
I'm looking forward to hearing from you.
