I have created a project using the Standard calendar as my base in Project Information. All tasks are effort driven, resource calendar also based on Standard calendar in Change Working Time. Confirmed Standard calendar as default in Tools\Options.
I inserted a column in the Gantt view for Task Calendar and all entries are showing as None.
I have inserted a column for Work, which is adding up fine.
I have also inserted a column for Duration which is not adding up at summary task level. Also, if I change the duration of a task, the Gantt chart is retaining the original value.
I think this must be related to calendars but I cannot see how to sort this out. Your help would be much appreciated.
