Custom Monitor&Alert does not work anymore

Hi,
some months ago I made a custom Monitor+Alert for NTFS or DISK problems in event viewer:

the Monitor+Alert was functional for long time, applied to many EP:

but in the last two months I don’t receive about any Alert and the Monitor seems to have no logs or activity.
A couple of days ago I connected a defective HD to my PC (so my event viewer has many disk events)
and no activity is shown.
Am I doing something wrong?
Thank you
