When you change the selection criteria, the download should follow immediately (except when using an API link to download the data).
Please go to "collected data" -> "view data" and keep an eye on the color of the CASE number. If it is grey, the case does not match the criteria. If it is black, it matches the criteria and will be included in the downloaded data set.
Please also check the number shown at the bottom of the "criteria" settings page.
