In the GDC Data Portal, when I filter by Experimental Strategy (e.g., RNA-Seq) in the Cohort Builder Available Data filter, why is this filter not working when I navigate to Repository?

Filtering in Cohort Builder results in a set of cases. Cases typically have available data for multiple Experimental Strategies (e.g., cases with RNA-Seq data can also have DNA-Seq data). As such, when navigating to Repository additional data besides RNA-Seq data is displayed. Repository filters are file based. When filtering Repository by Experimental Strategy (e.g., RNA-Seq) only files associated with the Experimental Strategy are displayed.
