Added a 5h slot to the Map Device

maybe I misunderstood what what adding 5 th slot to map device means . Does it mean that I will be able to use 5 scarabs with maps ? If that the case then after completing Maven's Invitation: The Atlas nothing changed on my map device .

Should be an extra slot, totaling five (then 6 when you get the 6th). Allowing for 4 fragments and 1 map.
