Tableau connector is not updating some rows from my Asana Project

I use the Tableau Web Data Connector to visualize my projects. But tableau is returning “Null” Values for some fields within rows even when I update them in Asana. Example

Imagine that Project 1 has 5 fields
Task 1, all 5 field values are reflected in Tableau
Task 2, only 3 field values are reflected in Tableau the other two display as “Null”

I’ve tried checking aliases, starting with a fresh connection in a new tableau workbook etc but nothing works. Does anybody know how I might fix this?
