SYMPTOM:
When using a dual axis graph in Strategy 9.4.x-10.x, if the metric value formatting is the same for each metric there will be no issues. However, if the formatting changes (one currency and one percent) then both of the graph axis's formatting becomes the same, taking on the currency as in the example below.
The two metric values are shown correctly on the graph:

After adding additional metrics to the graph notice the axis on the right how the scale changes:

CAUSE:
This is a known issue in Strategy 9.4.x-10.x.
ACTION:
Strategy will continue to investigate and post updates as soon as they are available.
