Modified Rule...

I use a number of KeyPass password wallets. These all sit in one folder and the files have the extension of KDBX.
I have set a rule that if all conditions are met:
Extension is KDBX
Date Last Modified did change.
The problem I have is that if I change a wallet, the file last modified changed from Today at 15:17 to Today at 19:31 the rule does not trigger.
If I preview the rule I get a Rule does not match' on the 'Date Last Modified did change'. I have also tried using 'Date Last Opened' and that has the same problem.
Any ideas as to how I can get it to work? Any help appreciated.
