Filter description is not being updated when using the Age group CDC

[pmallol]

Found in version 2.0.11

1. Create a new Report with assay 'Xpert Flu'
2. Add an 'Age group CDC' filter
3. Add a trendline chart and set 'Split by: Age Group CDC'
4. Uncheck the option '<1'

Obtained: the title does not refresh and still reads "Cases"

Expected: the title changes and now it reads: "1-4", "5-17", "18-24" and 4 other cases

In CDX (Version: 0.4-pre4) the same happens when using the 'Error code', 'Status', and 'Type' filters
