Edge Stable not blocking PUA downloads but Dev is blocking

I enabled the setting for Edge Stable and Edge Dev to block PUA downloads.  I then went to the website https://www.amtso.org/feature-settings-check-potentially-unwanted-applications/ to test that it works.  Edge Dev blocked the download but Edge Stable allowed it to be downloaded.  I verified that the setting to block PUAs was enabled.  Is there something else I need to do for the Edge Stable version to block PUA downloads?
