Duplicate Visualizations, Different Behavior

I literally copied a visualization and used different data sets with identical field and data structures, but I'm getting a different outcome in the visualization.

We're pulling our Azure and AWS hosting costs for month over month % change trend in the last quarter.

Both data sets are updated daily.  The MoM% was calculated identically, the vis filters are set identical (last 3 calendar months) however as you can see in below screenshots that one viz shows current month (April) + previous two, while the other viz shows the previous 3 months (not April).

Again, both data sources are updated daily, and both have data for the current month.

Quick edit, here are the MoM% formulas:

AWS Cost MoM% = 
IF(
	ISFILTERED('DateTable'[Date]),
	ERROR("Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column."),
	VAR __PREV_MONTH =
		CALCULATE(
			SUM('AWS Util'[AWS Cost]),
			DATEADD('DateTable'[Date].[Date], -1, MONTH)
		)
	RETURN
		DIVIDE(SUM('AWS Util'[AWS Cost]) - __PREV_MONTH, __PREV_MONTH)
)

And the Azure MOM:

Az Cost MoM% = 
IF(
	ISFILTERED('DateTable'[Date]),
	ERROR("Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column."),
	VAR __PREV_MONTH =
		CALCULATE(
			SUM('Az Util'[Az Cost]),
			DATEADD('DateTable'[Date], -1, MONTH)
		)
	RETURN
		DIVIDE(SUM('Az Util'[Az Cost]) - __PREV_MONTH, __PREV_MONTH)
)
