Was it working in a previous version? If yes, which was the last good one? Don't know

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). Nop

Please provide any additional information below.

Like I saied I created a mana text percent but when a new group member join it's showing 100% even if it's a war or a rogue.

I have to check "Hide mana of non healer players"  and uncheck it to fix. Reload work as well.

Also "Hide mana of non heal players" doesn't work in raid, all text mana are disable when check even for me (Healer).

In classic you cannot assign roles to players like in retail, all that stuff was disabled by blizzard, so all role related things in Grid2 are not applicable, because for the game the role of all players is always "none". 

Fixed in version r933
