Melee cannot use skills in duty mode. Because there is a check for melee classes to be in range to cast skills. IE melee range 3 y if not it wont cast anything.

can add this just under line 470 of the FFXIV_Helpers.lua

Code:

if (ml_task_hub:CurrentTask().name == "LT_DUTY" or
        ml_task_hub:ThisTask():ParentTask().name == "LT_DUTY") then
        return true

and make sure the melee character is not leader.
