SYMPTOM:
In Strategy Web 10.0, visualizations can be used as filters that target other visualizations. Data can either be filtered or highlighted on selection. However, when two or more visualizations are used as filters and set to highlight data on selection, the highlighting will not appear on any visualization also used as a filter set to hightlight data on selection as seen below.

In the image above, the firsrt 2 visualizations are filters set to highlight, and only the third visualization that has not been set to be used as a filter, highlights the data as designed. The other visualizations that are set to be used as a filters and highlight do not get highlighted at all.
STEPS TO REPRODUCE:

CAUSE:
This is an identified defect in Strategy Web 10.1.
ACTION:
Currently this issue is still being reviewed for feasibility by our Technology team and it is not scoped for any upcoming scheduled Strategy release.
