Fixed incorrect filter param being used after members import
Fixed incorrect filter param being used after members import

no issue

- after importing members a filter is applied to the members list only shows imported members
- the query param used for this was still using an old format which correctly updated the list but meant that the filter selection UI was left in a bad state that didn't correctly show the selected label or allow easy clearing of the bad filter
