When using "Windows Fine Grained Password Policies" the pass/fail colour indicators are sometimes incorrect. The following image shows Green for "Minimum Password Age" and Red for "Maximum Password Age". Both of these indicators should be Green.
The problem is with the regional format on the Password Manager Web Server and how the Password Manager application handles this.
If there is more than one Password Manage instance in the realm then this change should be applied to all of them.
Issue resolved in version 5.8.2
