I'm trying to set up a calendar that is a replica of the 5e calendar of Harptos and I'm struggling with getting the moon to display properly. I have 10 day weeks with 30 day months with a Cycle of 30 and shift of zero. I would expect the "new" moon to start on the 1st of each month and the Full on the 15th, but I don't see any of the phases changed.

1) Create and Calendar with 10 day weeks

2) 30 day months

3) 12 months in a year

4) Set cycle to 30 and offset to 0

Expected result is there should be a new moon on the 1st of each month, and a full moon on the 15th of each month. However I don't see the moon cycle phase change at all.
