If a dashboard (created using Analyzer Widgets prior to 6.5.2) has a date range filter on it AND the default value is set, that dashboard will no longer work.
The issue is that prior to 6.5.2, the default value was the "user friendly" version of a date range (i.e. Yesterday to Date, Last 30 Days). After upgrading to 6.5.2, those default values are no long "valid". Instead the default value has to be the numeric value that represents the "friendly" version (i.e. Yesterday to Date = 1, Last 30 Days = 3).
Upgrading to 22.214.171.124 will fix this issue.
As a workaround, it has been seen that removing the & in the default template value of the filter before saving it should work.
