filtering reports

I’d like to run a report (with pretty bar charts, etc) but filtered to specific dates.  We ran a 2nd iteration of an employee survey.  I can filter by date in some areas of Typeform to just the ones from the latest iteration, but the report section doesn’t have a date filter.  Do I need to delete the data from the prior round?  I’d rather keep it, but I’m not seeing a solution.  I tried duplicating the survey with the idea I could delete the old ones but just in a copy, but the results don’t come over when you create a duplicate.  Input from you experts?!?!  Thx!!
