What version of Grid2 and game type (classic or retail) are you using ?

retail 2.0.47

What steps will reproduce the problem? 

Create a debuff status for charging slash (172889)

Add charging slash to an icon indicator

enter iron docks and pull as many footsoldiers as you can find.

Observe you get multiple instances of the charging slash debuff.
Observe there is no stack counter on the icon when multiple debuffs are applied

  
Did you try having Grid2 as the only enabled addon and everything else disabled?

n/a

Was it working in a previous version? If yes, which was the last good one?

no

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack).

Please provide any additional information below.

There is a loss of information here. This specific debuff given is a great reason why. If a player has 2 of these debuffs in a high key it is a death sentence while 1 is completely managable. As far as i can tell there is no way to get that information in grid2. 

You can create an icons (plural) indicator to see multiple debuffs icons.

Icons (plural) is not the functionality I am talking about nor does it solve the problem. Using icons(plural) https://imgur.com/b3NDyNO here you can see what i mean. My character at the time of that screenshot has 2 of that debuff that i mentioned yet only one shows up in an icons and there is no indicator of stacks.

Edit: screenshot with more context: https://imgur.com/UF3nI8E. As you can see, there are 2 of the same debuff, 1 icon in the icons, no stack info.
