I've just purchased the calendar template and am working through my first deployment of it. I'm finding that the Add page is functioning differently depending upon where I select it from.
If I choose add from a Week View, the From & To field drop-downs correctly show the times in the increment set in the global settings. However, if I choose Add from any other view (monthly, day) then the From and To drop-downs show "30" (the increment set in global settings).
I've looked at the configurations for all these pages and cannot spot any differences. I have not modified any of the forms, this is how the template came.
