When I set this and other visual filters in a folder:
"48 Hours|Modified In The Last 48 Hours" ageM: <= 48 h
no files are being listed at all when some should certainly appear.
This is happening with XYplorer.exe /fresh as well, using say
"7 Days|Modified In The Last 7 Days" ageM: <= 7 d
Not sure exactly when this problem appeared, but very recently, perhaps related to the live filter improvement.
