Project plan header is not pulling/rolling up from sheet rows

Nat ✭✭✭✭

I just realised the top row is not rolling up percentages, dates or durations.

Dependencies are enabled, and the entire rest of the sheet is functioning fine (so I don't want to disable dependencies), but nothing is feeding that top row that feeds my reports. I just manually put in the start and end date - which should have come from level 2.

Does anyone have any idea how to start troubleshooting this?
