I'm using the default blizzard UI and I have noticed that for example: Coin of many faces on my bars displays as a 50 DAY COOLDOWN. Aswell as some potions being displayed as 8 hours while their ACTUAL cooldown is quite obviously a minute if I prepot them etc. When I open my spellbook Dispell Magic which is an offensive dispell without a cooldown is displayed as having a 36 minute cooldown sometimes, aswell as some very small icons on my targets with LONG duration having being displayed their remaining time like 59 minutes etc. even tho I have set the size of an icon for which to display the remaining duration/cooldown way bigger than any of the target/focus icons.

Do you have screenshots? Some of these cases could actually be related to some blizzard issues with returning cooldown duration info

I will take some tomorrow of the coin display bug aswell as the duration timers on very small icons and show you the current options of my addon setup. The cooldown display on spells/icons without an actual cooldown( aside from the gcd) is very occasional but i will try to snipe it whenever i will see it happening again.

Issues seem to have fixed themselves somehow without me touching anything (weirdly enough). I'll report if problems like these happen in the future.
