Power Bi averaging daily results to fixed budget

[Will38]

I am very new to Database work and Power BI.  I have been tasked with creating a report that will calculate our daily hours for inservice ambulances and create a chart to compare it to our budgeted hours.  I connected this very large database and built out a formula that looks at every shift start Date/Time and Stop Date/Time.  I used the subtraction tool and then converted duration to a number.  This all works.  When I try to bring this into a chart and use the date Hierarchy to include year,  quarter, month, day the averaging will not work.  It bring it down to shift level.  Is there a way to tally all the shifts in a day to compare it?  Thank you for helping this Rookie.  

This is a small sampling of the data.

In our database for me to calculate the number of hours each unit worked I must pull their start and end time for the shift.  I do this for each ambulance in the CAD.  After computing the hours and minutes for each unit placed in the CAD that day, I need to total daily hours.  then average it weekly, monthly, quarterly.  I have success averaging quarterly and monthly but when I try to go down to the day, using the date hierarchy, it goes all the way down to the individual shift average.
