The warning always pops up with any Shiny, only with the Shiny Hunt Achievements it might override the Shiny Pop-up, but you should know when you get such an achievement in the middle of a battle that you should watch for a Shiny at one of the entrances.

If you really want to be carefull you could always set your pokemon at a distance of the entrances or set their target to "Ignore Red".
