What version of Grid2  are you using (Version is displayed in General/About Tab) ?

Grid2 v3.0.24

What game client version, classic or retail, windows or mac and language are you using ?

Retail, Windows

What steps will reproduce the problem?

Created a new Status called "Defensives" where I enable both "Big Defensives" and "External Defensive Buffs". 
I used a new icons indicator that I called "defensives-icons" (number of max icons set at 3).
If you use both a defensive and an external defensive,for example, Barkskin and Ironbark for restauration drood, only one icon will be displayed. I noticed it is always Ironbark that is shown, as if External Defensive overrides Big Defensives.

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

Only Unit Frames addon I have.

Was it working in a previous version? If yes, which was the last good one?
Not Relevant. Was working before Blizzard Addons war.

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).
No error, but a bug I have identified.

Please provide any additional information below.

The normal behaviour for filters is: if two filters are specified only buffs/debufs that exist on both filters are displayed.

But blizzard decides the filters behaviour, not addons.

Hi Michael,

Thanks for the prompt response and the clarification.

Is there a way to see the spells that are under each category of Buffs/Debuffs. For example, I would like to know what spells belong to  "Big Defensives Buffs",  "External Defensives Buffs", etc

Thanks for your help.

I think not even blizzard knows at this point, this is a work in progress,  blizzard added those filter recently and they are changing and breaking things and adding or removing spells every few days.
