YoY KPI Visual

SITUATION - I was on my way to creating a visual depicting MoM, QoQ and YoY performance of certain metrics. The KPI visuals are working great for Mom and QoQ.

ISSUE - However, when I plugged them into the YoY, the target value is not populating (even though i validated that the metrics are populating correctly, big bold numbers at bottom of image). Why are the target values not populating in the KPI visual for YoY?

also, there are no differences in the filters applied to the visualizations. 

Any suggestions to help fix this? thank you
