Parent Roll-Up not working for % Complete and Dates

Hello,

These two column parent rows aren't working in random places of my project plan. Below are the column headers and example of a section where parent isn't calculating. I've read elsewhere that duration has to be a column to the dates to calculate but they are calculating fine in other places. If I need to add duration column back in...is there a formula I need to use?

Thanks,

DR
