Bug: nca_statistics file does populate groupings unless you view the Descriptive Statistics Results tab

[Plus-EV]

Description

If you run NCA and go directly to save and include NCA statistics as an output. The resulting NCA statistics does not include the groupings only the "Statistic" and "Parameter" columns.

To reproduce

1. Run NCA with default data set
   2a) Do not navigate to the Descriptive Statistics Results tab
   2b) Click save with NCA statistics selected
2. Resulting NCA statistics file will only contain the "Statistic" and "Parameter" columns.

Expected behaviour

Default grouping should be applied.

Note

The issues appears to come from input "summary_groupby" and how the choices are dynamically updated and generate. No choices are loaded until the Descriptive Statistics Results tab is viewed.
