There are 2 geomancer statuses for indicolure spells.

One is the actual effect of the spell, i.e. Haste, Attack boost, etc. That buff appears when you are close to the person that has the indi spell active and it disappears when you move far enough. This status has no duration as it acts like an aura.

Then you have the Indicolure buff that has allways the same status name and icon, this is the one that tells you how long left you have on your spell and it should be displaying a timer.
