“is within past month” doesn’t show entries within the past month but within the past 30ish days starting a month ago. We’re now in June. When filtering for entries within the past month I would expect getting entries within May which is the past month.
It would be great if this would work well.
Additionally I would suggest adding “this month” to the list too. This would help show something like sales from the actual month which doesn’t currently work as a filter as far as I can see, right?
