BAQ - JobOper Table, Actual Start Date Field null on every job

Hello, I’m trying to build out a BAQ and noticed that JobOper_ActualStartDate is blank for every row returned, no matter the table hierarchy, and even if this is the only table in the query.
I cannot figure this out. We’ve completed tons of operations for tons of jobs, we have values in Actual Costs and Actual Hours fields, just not Actual Dates. We even have values in LastLaborDate. The operations in question were completed either in MES or in Handheld. Any ideas?

Try looking in the LaborDtl table for the first date by Job/Asm/Opr.
