Incorrect skill cooldown

Class: Witch Doctor
Skill : Fetish Army
Issue : Cooldown
Summary:
when using the rune 'Devoted Following'. Cooldown for fetish army is reduced to 90 seconds from 120 seconds. When using this rune with the passive skill "Tribal Rites (which reduced the cooldown even further by 25%) it actually increases the cooldown to 98 seconds (what it says when the skill is highlighted). I haven't actually timed it to see if it is simply a misprint.
