Once a report filter has been applied, it doesn't seem possible to clear the filter without logging out of Koha.
This is in reference to the search filters on the reports page and I agree.
To clarify - if a filter is applied which finds no qualifying reports, there is an option to clear the filter. However, if the filter matches one or more reports and generates a list of reports based on the filter options, there is no way to subsequently clear that filter.
Is this still valid?
