Managed unit not getting results, find with same criteria does.

Hi

We have a virtual attribute which is a Date format and there is currently one user with a value in this.

I have created an MU to get users where this attribute is over 60 days ago, but there are no results, either in Preview Rule or clicking the MU. 

If I do a find in AR on the AD, using either the picker, or the Z format date (20240322000000.0Z) the user is found fine and if I get the MU criteria and then use Get-QADUser using this as the ldapfilter, I get the same reuslts as the AD find.

   

Does anyone know why this might be, am I missing something with the MU?

Thanks

Matt
